Aproximación a la Expansión de Espectro por Cuasi Muestreo

Abstract

Sampling the resultant signal has a spectral composition that includes the original signal can thus recover the original signal with the aid of a low pass filter. The actual sampling pulse using a periodic functionm, that is convolved with the signal, frequency to be sampled and results in the repetition of the spectrum of the sampled components on the sampler. In fact everything in the theorem is valid if the signal sampler, apart from having, a proper frequency, has continuous component. The question is what happens if this does not have DC component?
The response is only obtained spectrum expansion and recovery of the original signal must be performed with them, spectrum re-despansión temporarily multiply the signal with the sampling function without continuous.
