A cоntinuоus-time signаl x(t) is оbtаined аt the output of an ideal low-pass filter with cutoff frequency ωc = 500π radians. If impulse-train sampling is performed on x(t), for a sampling period Ts = 1ms, is it guaranteed that x(t) can be recovered from its sampled version using an appropriate lowpass filter?
