Write a MATLAB function that calculates the power Px of a signal over a time interval N using a sliding window of length N. (2.) Estimate the average power Px of different signals, sinusoid, square signal, and a speech signal.

i dont understand this requirement of my faculty if anyone can help me out with this.

here we need to generate normal sin wave then we need to use filters and after that this one comes i m stuck here i dont know what to do now.
