2 Impulse response FFT Familiarize or revise the concept of Fast Fourier Transform (FFT) . FFT can be used to do frequency analysing signals and systems. System frequency response is most easily obtained from the impulse response. Build a function which calculates 1 s long ftt of an impulse response and plot it with logarithmic frequency axis in db-scale. Impulse response is convoluted readily for you. Return the log-scale ftt for checking

Code:

function fft_exe = Exe2_2(IR, fs) % Remove all of this fft_exe = IR;
