Share This Topic: Type of Sampling in Communication Systems are classified as follows Ideal Natural Practical Flat-top(Sample and Hold) Ideal Sampling ( or Impulse Sampling) It is accomplished by the multiplication of the signal x(t) by the uniform train of impulses. Consider the instantaneous sampling of the analog signal x(t) Train of impulse functions select sample
