matlab code to generate frequency signal with RF values

Frequency in the range 3000Hz

Answer 1

[Honglei Chen]

I'm not sure what you mean but you can generate a 3000 Hz signal like below

f = 3000;
N = 1000;  % number of samples in signal
fs = 1e4;  % sampling rate
x = sin(2*pi*f*(0:N-1)/fs);

However I wouldn't consider 3000 Hz as RF, it is still in the audible range.

Answer 2

f = 3000;

N = 1000; % number of samples in signal

fs = 1e4; % sampling rate

x = sin(2*pi*f*(0:N-1)/fs);
