¥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?
