Question

An analog signal has a duration of 200 seconds. The spectral content ranges from near dc to 5 Is. The signal is to be sampled, converted to digital format, and stored in memory for b sequent processing. To assist in recovery, the sampling rate is chosen to be 20% above the cortical minimum, (a) Determine the sampling rate, (b) Determine the minimum number of samples that must be taken if reconstruction is desired.
