| Dec 10, 2020 at 15:24 | comment | added | Noha | Do you mean the following: although the number of encoding bits in differential pcm is larger than delta modulation, efficient compression can be achieved using this technique, since its sampling rate is lower than the sampling rate in delta modulation, and also entropy coding techniques can be employed after differential pcm to send the data with minimum number of bits? | |
