The function f(t)=3cos(500πt) + 5cos(800πt) issampled digitally at a sampling rate of 400 Hz, starting attime t = 0.00025 s.

(a)Calculate the frequencies that you would expect to see on a frequency spectrum of the sampled data.

(b)If you did Part (a) properly, one of your answers should be 0 Hz, which means that aliasing leads to an effective DC offsetin the perceived signal. Calculate this effective DC offset in volts.
