Question

4. A waveform x(t)s 20cos (1000π + ) cos (2000π + ) is to be uniformly sampled for digital transmission. a) What is the maximum allowable time interval between b) If we want to reproduce 1 hour of this waveform, at least c) Using NRZ antipodal coding and A/D with total 256 level of sample values that will ensure perfect signal reproduction? how many sample values need to be stored? quantization level. What would be maximum time per bit (i.e. bit-duration Tb) olution:
