Abstract :
The letter describes a method of improving the dynamic range of a continuously variable slope delta modulator (CVSD). This is achieved by modifying the basic step size ¿0 Compared to the CVSD algorithm, the modified CVSD (MCVSD) algorithm yields about 15¿20 dB dynamic range improvement without degrading the peak SNR and the bit error rate tolerance.
