In delta modulation the bit rate is:
WebFeb 7, 2024 · Delta Modulation (DM): It is used to reduce the bandwidth or bit rate. It is considered as a 1 bit DPCM. So, the encoder is a 1-bit ADC The encoder output is either 1 or 0 Two quantization levels are used + Δ and - Δ The block diagram is shown below: DM uses past information for modulation. India’s #1 Learning Platform 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'.
