Perancangan Sistem Pendeteksi Suara Dari Bluetooth Receiver Dan Audio Sound System Pada Kontes Robot Seni Tari Indonesia
2018Co-Authors: Bimantara, Tommy Eka PutraAbstract:Berbagai kompetisi yang diadakan oleh KEMRISTEKDIKTI menjadi salah satu wadah pengembangan teknologi robotika, salah satunya Kontes Robot Seni Tari Indonesia (KRSTI). Musik yang digunakan pada arena perlombaan berubah tiap tahunnya sesuai dengan tema yang ditentukan oleh panitia. Robot yang dibuat harus memiliki kemampuan untuk mendeteksi musik melalui Bluetooth yang digunakan saat lomba berlangsung, sehingga diperlukan sistem yang mampu menyesuaikan output dari Bluetooth yang dapat dibaca oleh sistem utama. Seringkali bluetooth mengalami disconnect dan tidak pairing saat perlombaan berlangsung dan tidak dapat mendeteksi suara dari audio sound system sebagai antisipasi jika bluetooth dalam keadaan disconnect sehingga peserta perlu melakukan retry yang dapat mengurangi poin. Berdasarkan latar belakang tersebut pada skripsi ini dirancang sistem yang mampu mendeteksi keadaan bluetooth receiver. Keadaan bluetooth disconnect dapat dideteksi dengan dengan mencuplik sinyal dari led yang terdapat pada bluetooth receiver. Penentuan keadaan bluetooh diolah oleh mikrokontroler sebagai penentu sistem yang diproses antara bluetooth reveiver atau sound sensor. Karena output dari bluetooth receiver yang sangat kecil dalam orde millivolt maka perlu dikuatkan 101 kali menggunakan penguat non-inverting amplifier. Penentuan ada tidaknya lagu pada bluetooth receiver diperoleh dengan mengamati pada frekuensi berapa lagu mulai mengalami peningkatan menggunakan software frequency analysis pada Adobe Audition sebagai frekuensi cut off pada Highpass Filter. Keberhasilan Highpass Filter diketahui dengan membandingkan besar penguatan tegangan dan decibel secara teori. Saat mikrokontroler mendeteksi bluetooth dalam keadaan disconnect maka sound sensor akan memproses suara dari audio sound system. Output Filter dan sound sensor itulah yang akan diolah mikrokontroler sebagai penanda ada tidaknya musik pengiring. Hasil pengujian bluetooth didapatkan sinyal 0 dan 1 saat bluetooth dalam keadaan disconnect dan bersinyal 0 saat bluetooth dalam keadaan connect. Mikrokontroler berhasil membedakan keadaan bluetooth dengan menggunakan perhitungan (counter) dan dapat menentukan mana sistem yang diproses. Pengujian Highpass Filter dengan frekuensi cutoff 1000 Hz didapatkan penguatan sebesar 0,6667 dalam tegangan (v) dan 3,52 dalam decibel (dB) yang mendekati penguatan secara teori sebesar 3dB dan sudah memenuhi spesifikasi yang dirancang. Sound sensor yang dirancang berhasil menghasilkan sinyal listrik dengan amplitudo yang besar saat menerima suara musik pengiring dari audio sound system dan menghasilkan amplitudo yang kecil saat musik pengiring distop. Perbedaan amplitudo digunakan acuan oleh mikrokontroler dengan menghitung selisih nilai pembacaan ADC dan berhasil menghidupkan led indikator saat mendeteksi ada musik

Study of multi-channel wideband receiver architectures.
2013Co-Authors: Lesellier AmandineAbstract:Cette thèse est le fruit d'un partenariat entre la BL TVFE de NXP Semiconductors et l'ESIEE dans le cadre d'une thèse CIFRE. Le but est d'apporter une solution qui permette la réception de plusieurs canaux pour le câble. Ce sujet est lié à la problématique de numérisation large bande. Dans la première partie, nous faisons un état-de-l'art sur les convertisseurs analogiques-numériques (CAN), sur les architectures parallèles (entrelacement temporel et bancs de filtres hybrides (BFH)), et sur les méthodes d'échantillonnage (passe-bande et complexe). Puis, nous étudions une architecture composée d'un banc de filtres analogiques et un banc de CANs. Nous cherchons à réduire surtout le taux d'échantillonnage. Nous comparons notre solution à un CAN large bande performant, avec notre fonction de coût. L'un des avantages de cette architecture est que tous les composants sont faisables, même les CANs, et qu'il est possible d'éteindre des sous-bandes pour diminuer la consommation. Cette solution est intéressante pour le moment mais n'est pas compétitive en termes de consommation et de surface. Nous proposons une alternative dans la partie 3, avec les BFH. Nous étudions cette architecture, en gardant à l'esprit la faisabilité de la solution. Nous avons choisi un BFH à deux voies, avec un filtre analogique passe-bas et un passe-haut. Puis, nous proposons un algorithme d'optimisation des filtres de synthèse pour atteindre nos objectifs de distorsion et de réjection de repliement. Une identification des filtres analogiques est aussi présentée. Finalement, une réalisation physique prouve le concept et valide les limitations théoriques de cette architectureThis thesis is a partnership between the BL TVFE of NXP Semiconductors and ESIEE. Its goal is to provide a solution to multi-channel reception for cable network. This is linked to the problematic of broadband digitization. In the first part, the state-of-the art of ADCs, parallel architectures (TI and HFB) and sampling methods (bandpass sampling and complex sampling) is recalled. Then we study an architecture called RFFB with a bank of analog Filters and a bank of ADCs. We try to reduce the constraints on ADCs, especially the sampling rate with the different sampling. We propose an interesting solution to broadband digitization and compare this solution to a challenging wideband ADC, using the cost function we introduce. This architecture has the major advantage that all the components are feasible, even the ADCs, and it is possible to switch-off subbands to save power. It could be a good solution at the present time but it is not competitive in terms of power consumption and surface. An alternative is proposed in Part 3, where we study Hybrid Filter Banks. It is interesting to study this architecture with realization feasibility in mind. This is why we select a 2-channel HFB with a lowpass Filter and a Highpass Filter as analog Filters. Then we propose an efficient optimization algorithm to find the best synthesis Filters and reach our targets of distortion and aliasing rejection. An identification of analog Filters is also suggested to cope with the issue of sensitivity to analog errors. Finally, a physical realization proves the concept of aliasing rejection and confirms the theoretical issues of this architectur

perancangan Filter bandpass dengan teknik penggabungan Filter lowpass dan Highpass
2018Co-Authors: Fitri Farida, Eko SetijadiAbstract:UWB technology started to become an attraction in the field of research since the Federal Communications Commission (FCC) allowing this communication is used for commercial communications at a frequency (3.1 GHz - 10.6 GHz). UWB has a very wide frequency range so that in practice there is often interference due to signal interference. Therefore in UWB system Filter design is required to maintain UWB device. In telecommunications, Filter is a transmission device that has the function to pass the desired frequency. In this paper designed bandpass Filter which is applied for UWB technology. The designed bandpass Filter is a combination of a lowpass Filter (LPF) and a Highpass Filter (HPF). The lowpass Filter has the characteristic of passing a frequency lower than its cut-off frequency. The Highpass Filter has the characteristic passing a frequency higher than its cut-off frequency. Considering the characteristics of both Filters, the bandpass Filter (BPF) is a combination of lowpass and Highpass Filters. In this research designed lowpass Filter in microstrip technology with step impedance method, that is by combining high impedance microstrip and low impedance microstrip with a certain length. As for designing HPF using the distribution method of short circuit stubs by adding via ground on each stub. The design of this Filter uses Roger substrate RT 5880 with dielectric constant er = 2,2 with thickness (h) = 0.508 mm. In this research it can be concluded that bandpass Filter can be designed with lowpass and Highpass Filter incorporation method, although at the merging of Highpass and lowpass structures is disturbed by each other, but overall design shows matching bandpass.
