WebIn a PCM system, a five bit-encoder is used. If the difference between two consecutive levels is 1V, then the range of the encoder is 0 – 30 V 0 – 31 V 1 – 30 V 1 – 32 V Answer 3. If the number of bits per sample in a PCM system is increased from 8 to 16, then the bandwidth will be increased 4 times 2 times 16 times 8 times Answer 4. Web19 sep. 2024 · Since bandwidth is the width of the spectrum and spectrum is a range of frequencies, bandwidth is measured in Hertz or khz or mhz. 2. Data Rate: Data Rate is defined as the amount of data transmitted during a specified time period over a network. It is the speed at which data is transferred from one device to another or between a …
