MATLAB problem

FIR Filter Homework Assignment 1. Design a minimum order FIR filter for the following specifications (Use the remez filter): the relative specification is provided as below, where R, -ldB, R 20dB 0 dB 1 dB 20 de 03 05 Use a trial and error process to figure out the minimum order of the filter that satisfies the given To help you in your process you must use the line command in MATLAB Line(x,y) will plot lines on your filter plot, where x and y are vectors of the x and y coordinates of the points that are to be joint using lines, Use this command to draw the lines representing the specifications as shown above. 2. Use the filter to remove the noise component from a signal that is sampled at 1000 Hz, and has a combination of 200 Hz signal (Amplitude 100) and a 450 Hz signal (Amplitude 10). Fs-1000 s= 100"sin (2"pi*t"200) + 10.sin (2*pi*t+450); 3. Show the signal before and after filtering 4. Show the normalized FFT of the signal before and after filtering FIR Filter Homework Assignment 1.
