WebSo, in the delta modulation scheme, we can say, Bit rate = Pulse rate = Sampling rate Because we're only allocating 1 bit/sample, the number of levels is L = 2^ (1) = 2. In general, the highest level is represented by '+∆', while the lowest level is represented by '-∆'. From the quantizer value we decide whether the sampling bit is '1' or '0'. WebNov 26, 2024 · Delta modulation bit rate (r) = Number of bits transmitted/second = Number of samples/sec x Number of bits/sample = f s x 1 =f s Therefore, the delta modulation bit rate is (1/N) times the bit rate of a PCM system, where N is the number of bits per transmitted PCM codeword. movie snacks themed dinner
