Fs = 1000; T = 1/Fs; L = 1001; t = (0:L-1)*T; y1=110*sin(2*pi*50*t); y2=10*sin(2*pi*250*t); z=y1+y2 f = Fs*(0:(L/2))/L; z=abs(fft(z)); figure(1); semilogx(f,z(1:numel(f)));xlabel('Frequency(Hz)');

The demo on Remove the 60 Hz Hum from a Signal has everything you need. You only need to change the frequency parameters.
