A noiseless 4 kHz channel is sampled every 1 msec What is the maximum data rate?

by Nyquist theorem
max data rate = 2H log2 V bits /sec
so H= 4KHz..
and v=2 ( say binary is transmitting )
therefore
max data rate = 2 * 4 *103 *log22 bps
max data rate = 8000 bps
Bcoz it is sampling per 1ms
so

Why are analog waveforms sampled 8000 times every second?
The frequency range for a voice signal is 300 to 4000 HZ. The Nyquist theorem states a waveform should be sampled at 2 times its highest frequency. So 2 x 4000 is 8000 samples every second. This ensures an adequate representation of the signal.
