Question

Consider the example of discrete time (DT) processing of continuous time (CT) signal we discussed in Friday lecture, where we had a low-pass nilter DT LTI system. Suppose that the input r(t) and the DT LTI system (i.e.. H(e?) are fixed to the examples we used in the lecture. What would happen to the output yr (t) if the sampling frequency grows to infinity? (a) The value of yr (t) at all time points will converge to zero. (b) The value of yr(t) at all time points will grow to infinity (c) y(t) will become r(t

Explanation / Answer

C)

EXP)as sampling frequencey tends to 0 then Ts(sampling interval) in time domain becomes 0.As inverse of sampling frequency gives us the sampling time period.now there's no sampling occurs so there remains sampled signal will be original signal only i.e x(t).
