A signal, x(t) = 20 cos (1000?t) is impulse sampled at a sampling rate of 2000 samples/second. Graph two periods of the impulse-sampled signal x?(t) . (Let the one sample be at time, t = 0.) Then graph four periods, centered at 0 Hz, of the CTFT X?( f ) of the impulse-sampled signal x?(t) . Change the sampling rate to 500 samples/second and repeat.
