The bit rate for a signal, which has a sampling rate of `8 kHz` and whare `16` quantisation levels have been used isA. 32000 bits/secB. 16000 bits/secC. 64000 bits/secD. 72000 bits/sec |

Answer» Correct Answer - a If n is the number of bits per sample, then number of quantisation level`=2^(n)` Since the number of quantisation level is `16` `implies 2^(n)=16impliesn=4` `:.` bit rate = sampling rate x no. of bits sample `=8000xx4=32,000 " bits"//"sec"`. |
