The probe band limited signal with fmax= 1Mhz was transmitted during the time T0=2 minutes.
a) Find the maximum number of samples (N) that can be sent through the channel during T0 without losing of information.
b) Find the sample rate (samples/s)
c) If PCM is used to transmit the probe signal in digital format (with μ = 255), how much bits (K) should be sent through the channel during T0 if the S/N ratio required is 20 dB.
d) if PCM is used to transmit the probe signal in digital format (with μ = 255), find the bit rate (bits/s) for S/N ratio 20 dB.
