in natural sampling,an analog signal g(t) is multiplied by aperiodic train of rectangular pulses c(t).pulse repetitionfrequency of this periodic train is fs and theduration of each rectangular pulse is T(with fsT,,1). find thespectrum of the signal s(t) that results from the use of naaturalsampling,assuming that time t=0 corresponds to the midpoint of a rectangular pulse in c(t). show that the original signal m(t) may berecovered exactly from its naturally sampled version,provided that the conditions embodied in the sampling theorem are satisfied.
