Description

When one increases the duty cycle up to 100% what is observed on the DSO is a wave that is a straight line which resembles a DC wave, while when you lower it to 0% it becomes a set of impulses.

As you slowly decrease the frequency of p(t) from 7kHz aliasing starts to occur upon reaching 5kHz.

What we observed relates to the Nyquist’s criterion as the signal we observed in the lab wasn’t twice the bandwidth of the sampled signal, therefore we couldn’t achieve a perfect reconstruction and saw aliasing.

The range of the LPF doesn’t reject the signal component. Also consider the effect that the bandwidth limiting will have on the reconstruction of the signal in whether the information that can be retained from the sampling will be shown, or there will be loss of information....
