USE RECTANGULAR WINDOW METHOD AND MATLAB PLOTS AND CODES AS WELL. PLEASE COMPLETE ALL PARTS.

PROBLEM #1 FIR WINDOWING METHOD Design a Low Pass FIR Filter with the following characteristics: Passband 10kHz, Stopband 11kHz, and Sampling frequency 44kHz. Use window rectangular and filter length of 264. Answer the following questions: 1) Determine the specs of the ideal LP desired, and sketch its frequency response. 2) Find and sketch the impulse response h(n) by hand. 3) Use MATLAB to plot the frequency response of the filter you designed. 4) Comment on the expected performance of the filter you designed.
