¥Match the fundamental frequency of the signal
to the sampling interval. If the sampling interval contains an integer number
of signal periods, the harmonics of the periodic signal will appear as sharp
peaks on the amplitude spectrum.
A rectangular wave with a frequency of 2000 Hz must be sampled with a
Digital Spectrum Analyzer that samples at a rate of 500,000 samples per
second. How many samples should be
taken if the sampling interval must contain 15 complete waveforms?
