Question

An analog signal has a 1 hour duration. The spectral content ranges from near dc to 4 kHz. The signal is sampled, converted to digital format, and stored in memory for subsequent processing. To assist in recovery, the sampling rate was chosen to be 50% above the theoretical minimum. (a) Determine the minimum number of samples that must be taken if reconstruction is desired. (b) Determine the time interval between successive samples.
