Noun
Dirac comb (plural Dirac combs)
(mathematics) A periodic tempered distribution constructed from Dirac delta functions for some given period. It allows both continuous and discrete phenomena to be represented in a single framework.
Another commonly used frequency domain representation uses the Fourier series coefficients to modulate a Dirac comb : : where f represents a continuous frequency domain. Source: Internet
