Ahmad is a senior electrical engineering student. During Ramadan, he like listening to sheik Nabil Alrefa'ee and recording his recitation during altraweeh prayer. Unfortunately, when Ahmad arrived home, he found that the recording was corrupted with noise in addition to one high undesired echo component. If x(n) is the discrete clean sound of the imam, then the recorded sound (called Recorded_Signal) y(n) can be modeled as: y (n) = ax(n-no) (1) where a and no are constants. Fortunately, Ahamad managed to find a test sound signal where both the input and output of equation (1) are known, called Test_Signal and Recorded_Test_Signal. In this project, your task is to do the following: 1- Load the Projct_Files.mat file. 2- You can listen to a sound signal in MATLAB using the command sound. For example, you can type sound (ASignal, Fs) where ASignal is any audio signal and F's is the sampling frequency. Listen to Recorded_Signal. What do you notice? 3- Using the test signals, find the impulse response of the system in equation (1). Find a and no. 4- Recover the signal x(n): You need to find an inverse system (a zero-forcing filter hzf(n)) that take y(n) and produce an estimate to x(n): ✰(n) = y(n) * hzf(n
