Hi , I am supposed to take 64 samples from a sine wave and perfrom 256 point DFT how can i do that..
please check if this code is correct
%%%%%%%%%%%%%%%
Fs = 30; % Sampling frequency
t = 0:1/Fs:1; % Time vector of 1 second
n = 64;
f = 8;
x = cos(2* pi*t*f*n);

Fs = 30;
dt = 1/Fs;
N = 64;
t = dt*(0:N-1)';
Fc = 8;
x = cos(2*pi*Fc*t);
M = 256;
