How can I make the FFT transform from this sine wave with noise code?
古いコメントを表示
Hi, I want to make FFT transform from this sine wave with noise code,
Fs = 8000;
dt = 1/Fs;
StopTime = 0.06;
t = (0:dt:StopTime-dt);
A = 4;
Fc = 60;
snr = 10;
x = A*sin(2*pi*Fc*t);
y = awgn(x,snr);
plot(t,y);
xlabel('time (in seconds)');
title('Signal versus Time');
Anyone could help? Thank You
