Abstract
Audio signal information with high quality would help the television audience to increase the perception of the information displayed. Transmission channel capacity will become limited, while the need of channel communication is increased. The research aim is coding the audio signal on the low bit rate for saving the channel communication usage for digital television broadcasting. The research will be done is develop an audio signal coder on the low bit rate with the suitable decoder. The proposed audio signal coder consists of signal existention detector, period width detector, average amplitude counter, separation of the vibrating and the nonvibrating signal, determination of the period signal and parameters coding. One period signal is coded using sinusoidal model. The decoder consists of the parameters detector, signal synthesizer, and the periodic signal generator. The research results contribution for digital broadcasting is the method developing for decreasing the audio signal rate. So that the communication channel usage can be saved.
