Abstract

Telah dibuat sistem pengirim data digital bersama sinyal audio melalui pemancar FM stereo. Sistem pengiriman data ini berdasarkan prinsip FDM (•equency deviasi multipleksing). Pengiriman data dilakukan dengan memodulasi amplitudo frekuensi sub pembawa 67 kHz dan digabungkan dengan keluaran multiplekser FM stereo sebagai masukan pemancar FM. Pdodean kembali data dimulai dengan pemisahan data digital ten-nodulasi amplitudo dengan sinyal audio menggunakan rangkaian band pass filter(BPF). Keluaran BPF dilewatkan penguat penyangga, detektor dan penyulut Schiint untuk mendapatkan kembali data digital. Sistem telah dapat mengirim data digital sebesar 1kHz bitidetik dengan bentuk sama dengan data yang dikirim. A digital data transmitter system that utilizer audio signal of stereo FM transmitter has been made. The data transmissian system is based on frequency deviation multiplexing (FDM) principle. The data transmission was conducted by sub carrier frekuency 67 kHz the amplitude modulizing and combained with the stereo multiplexing output to be FM transmitter input. The data decoding was started by separating the amplitude modulized digital data and the audio signal using band pass filter (BPF) circuit. The BPF output therefore was passed through buffer amplifier, detektor and Schimt triger to regain the tramsmitter data. The system has been capable to transmitter the digital data up to 1 Ithit/second that has equal form with the transmistter one.
