A signal \(x(t) =\frac{sin6000πt}{πt}\) is sampled at 75% higher than the Nyquist rate. The signal is further encoded using PCM with 512 quantum levels. The resulting PCM data in a polar NRZ format is transmitted through the channel using M-ary PSK. The minimum bandwidth (B) required for different values of M will be.
1
For M = 4, B = 94.5 kHz
2
For M = 4, B = 47.25 kHz
3
For M = 8, B = 63 kHz
4
For M = 16, B = 47.25 kHz
