crapth wihite noise in matlab

To generate white noise in MATLAB, you can use the randn function which generates random numbers from a standard normal distribution. Here's an example code snippet to generate white noise:

main.m
% Specify the length of the white noise signal
N = 1000;

% Generate white noise signal
white_noise = randn(N, 1);

% Plot the white noise signal
plot(white_noise);
title('White Noise Signal');
xlabel('Time');
ylabel('Amplitude');

In this code snippet, we first specify the length of the white noise signal (N), then use the randn function to generate N random numbers from a standard normal distribution, hence producing white noise. Finally, we plot the white noise signal to visualize it.
