(a) Plot the spectrum of a PAM wave produced by the modulating signal m(t) = Am cos(2fmt) %3D assuming the modulation frequency fm duration 0.2 Hz, sampling period T, 1s, and pulse %3D T = 0.45s (b) Using an ideal reconstruction filter, plot the spectrum of the filter output. Compare this result with the output that would be obtained if there were no aperture effect.

The analog-to-digital converter (ADC) allows circuits controlled by microprocessors, Arduinos, Raspberry Pi, and various reasonable digital circuits to be connected to the real world. In the real world, analog signals have a continuous stream of informat…
