Dirac Comb
In
mathematics
, a
Dirac comb
is a
periodic
Schwartz distribution
constructed from
Dirac delta functions
\delta_T(t) = \sum_{n=-\infty}^{\infty} \delta(t - n T)
for some given period
T
.
Sampling and aliasing
Multiplication of a
continuous signal
by a Dirac comb is sometimes called an
ideal sampler
with
sampling rate
T
. When used as an ideal sampler, it can be used to understand the effects of
aliasing
and as a proof of the
Shannon-Nyquist sampling theorem
.
See
Shannon-Nyquist sampling theorem
for a proof using the Dirac comb.
