The desired signal of maximum frequency (fm)  centred at frequency fc=0   may be recovered if The sampled signal is passed through low pass filter Filter has the cut off frequency fm Both of the above None of the above

nyquist criteria sates that original signal can be reconstructed by passing samples through a Select one:a. LPF with cut off fmb. HPF with cut off fmc. HPF with cut off fsd. LPF with cut off fs

A continuous-time signal x(t) is obtained at the output of an ideal lowpass filterwith cutoff frequency We = 1,000'77'. If impulse-train sampling is performed on x(t),which of the following sampling periods would guarantee that x(t) can be recoveredfrom its sampled version using an appropriate lowpass filter?(a) T = 0.5 x 10- 3(b) T = 2 X 1o- 3(c) T = 10-

Your goal is to achieve as flat of a frequencyresponse as you can when all the frequency response of all filters are added ± 1dB is a good goa
