Impulse Sampling
The spectrum of the impuse sampled signal is the spectrum of the
is the^ s Hz, where f^ s unsampled signal that is repeated every f
sampling frequency or rate (samples/sec). This is one of the
basic principles of digital signal processing, DSP.
Note:
This technique of impulse sampling is often used to
translate the spectrum of a signal to another frequency band that
(^) .s is centered on a harmonic of the sampling frequency, f
(^) >=2B, (see fig 2-18), the replicated spectra arounds If f
do not overlap, and the original spectrum can^ s each harmonic of f
(^) /2.s be regenerated with an ideal LPF with a cutoff of f
s
