Question

4.explain in a couple of sentences why it makes sense to use a second-order low-pass butterworth filter to track the square wave r(t).

Answer 1

Answer:A second-order low-pass Butterworth filter is ideal for smoothing signals and removing high-frequency noise

Step-by-step explanation:

A second-order low-pass Butterworth filter is ideal for smoothing signals and removing high-frequency noise, which makes it a suitable choice for tracking a square wave signal. By removing the high-frequency components, the filter can provide a stable and accurate representation of the underlying square wave signal, making it easier to track and analyze.
