show the MATLAB Code with comments and

Write an .m file in MATLAB, that records audio (you can record your own voice for 20 seconds), takes Fourier transform of the signal (probably FFT).

Solutions

Expert Solution

Code:

rec = audiorecorder(96000,16,1); %created object rec for audio recording with default parameters
recordblocking(rec, 20); %recording the sound using object for 20 s
play(rec); %play recoding recorded
y = getaudiodata(rec); %get the data recorded in double format
figure(1);
plot(y); %plot of the recorded signal
tsignal = fft(y,100); %taking fourier transform of the signal recorded

Write a .m function file on MATLAB that reads the parameters stored in the file missile data.txt into MATLAB. The function should have the following declaration: function [X0, Y0, Z0, m0, mf, Thmag0, theta, phi, Tburn] = read input( input filename, M id) where input filename is a string variable denoting the name of the file to be read and M_id is an integer which denotes the missile ID. The outputs are the initial position (X0, Y0, Z0), initial and...

a – DSB. Write the code for an m-file (script) to generate a DSB signal. The modulating (message) signal is a single tone signal with frequency 1kHz and the carrier frequency is 30kHz. Time Vector: 3001 points over range from 0 to 3ms (3 cycles of the modulating signal). Plot your original message signal both in time and its spectrum. (Note: the Matlab examples 6.1 and 6.2 will help, but use the cosine functions for your signals instead of sine...

Need explanation of MATLAB code which creates echo. (SIGNAL PROCESSING) If the original audio signal is x(t) then the echo is y(t) = x(t) + alpha*x(t-delay) This code below creates this echo however I don't understand how every line of the code works, could someone comment this code so I can understand? [x,Fs] = audioread('Hallelujah.wav'); sound(x,Fs); delay = 0.5; % 0.5s delay alpha = 0.65; % echo strength D = delay*Fs; y = zeros(size(x)); y(1:D) = x(1:D); for i=D+1:length(x) y(i)...
