The continuous signal m(t) = 2 cos(400πt) + 6 cos(900πt) is sampled using an ideal sampling function.

(a) Sketch the frequency spectrum of the sampled-data signal if TS = 1 (ms).


(b) Sketch the frequency spectrum of the sampled-data signal if TS = 0.5 (ms).


(c) Determine the minimum satisfactory sampling frequency.
