set fundamental to 0dB using snr

Dear Sir/Madam,

How do you adjust the snr plot so that the fundamental is at 0dB?

Fs = 10000;

f = 2100;

t = 0:1/Fs:1;

x = 5*sin(2*pi*f*t) + 0.001*randn(1,length(t));

snr(x, Fs, 5);

Regards Joe

Dividing ‘x’ by ‘max(x)’ is probably as close as you can get:

xs = x/max(x);

figure(1)
snr(xs, Fs, 5)
