The minimum channel bandwidth required is 6 MHz. If the samples are encoded with n-bits/sample then. the number of bits n is equal to 10. No worries!

What is the bandwidth required for a PCM system?
The bandwidth requirement is 2fmax · n/2 = fmax · n = 4fmax, or four times the analog signal requirement. Note: for PCM the necessary transmission bandwidth is simply the analog signal bandwidth multiplied by the bit depth.
What is the formula for channel bandwidth BW in PCM?
BANDWIDTH OF PCM SIGNALS Bandwidth of serial PCM signal depends on the bit rate and the pulse shape. The bit rate is R R = nfs n = number of bits on the PCM word ; M = 2n fs = sampling rate For no aliasing: fs = 2B, where B is the bandwidth of the analog signal that is to be converted.
How do I calculate minimum channel bandwidth?
Minimum Transmission Bandwidth (Using Ideal Nyquist Pulses)
As seen the bandwidth required is (Rb)/2 (∵Rb =1/Tb) for the Nyquist pulse shown above. It is the peculiar scheme of overlapping signals that results in minimum transmission bandwidth.
What is the required bandwidth of a PCM system for 256 quantization levels?
B.W. = 3.072 MHz
