Hello, I have been asked to: - design an LPF with a cut off frequency of 17kHz and a roll-off of 40dB Decade. I have attached a picture of the circuit diagram I came up with. Can someone please confirm if I have this correct ? The second part of the question was: - prove both time domain and frequency domain plots for the output waveform for the above filter, if a 5kHz square wave was applied to it. For this question I am rather lost. Can someone please give me some guidance on how I would display these 2 graphs. I cant find anything in my notes directly explaining how to do this. Thanks kindly for any help.
