Alan Jox → y using h
just to show all filter design is same for every case when signal has ideal condition (Band limited, LTI System ). All analogy assume that we know the original continuous function
- s stands for sampling, d stands for discrete
- c stands for continuous
The factor in the equation accounts for the fact that each sample contributes a term of to the frequency domain representation
Sampling → discrete processing → Lowpass filter → Gain → De-sampling
