Describe natural sampling with neat sketch.
1. Natural Sampling or Chopper Sampling
Natural Sampling is a practical method of sampling in which pulse have finite width equal to T. Sampling is done in accordance with the carrier signal which is digital in nature.
With the help of functional diagram of a Natural sampler, a sampled signal g(t) is obtained by multiplication of sampling function c(t) and the input signal x(t). Spectrum of Natural Sampled Signal is given by:
