Can you please just answer part 2! Thank you
1. Suppose x(t) is a square wave of fundamental frequency 1000 rad/s. It gets processed by an ideal low-pass filter with cut-off frequency 1200 rad/s. Sketch the output of this filter, y(t). Suppose we want to process y(t) digitally and be able to fully reconstruct it. What is the minimum necessary sampling frequency to do so?
2. Suppose we wish to digitally process and fully reconstruct the same x(t) from before. Would it be a good decision to keep the low-pass filter? Why or why not? Would it be possible to fully reconstruct x(t)? If so, what is the minimum sampling frequency necessary to do so?
