The Delta/CVSD Decoder is demodulates the Delta or CVSD modulated signal from the Delta / CVSD Generator and recovers the original analog signal. Using the Delta/CVSD Decoder, students gain an understanding of Delta / CVSD demodulation techniques. Distortion of the modulated signal due to slope overload or weak and noisy signals can be studied, as well as the effects of noise on the transmitted signals.
