Question 6 0 out of 4 points Suppose that a continuous time signal xis bandlimied bz and it is prob a CTsystem with transfer function H(5) and reconstruction to replace the CT system Select a suitable sampling rate. Suppose that a continuous time signal x(t) is bandlimited by 1Hz and it is processed by a CT system with transfer function H(S)for noise clean-up. We want to design a DT system with ideal sampling 5rnoise clean-up. We want to design a DT system with ideal sampling S+1 Answers: 10 Hz 1Hz 1 rad/s 2 rad/s

Solution

part-1 2Hz

part-2 half of sampling frequency-1Hz

part-3 H_DT(jw)=H(jw)

part-4 1Hz

part-5 the ZOH for reconstruction must have the same sampling rate as the sampling impluse train
