If that is what you want, Search for the term "noise" in Simulink window, and keep clicking "F3" button until you reach the mentioned component. Regards

Here is an example, where fcentral = 50Mhz, fupper = 52 MHz, flower = 48 Mhz, fstop = 70 Mhz: Code: Noise=0.7*(randn(size(t))); % Noise signal fc = 50e6; fup = 52e6; flo = 48e6; fs = 70e6; Wp = [flo fup]/(fs/2); % normalized passband interval Ws = [(fc/2) (fc+(fc/2))]/(fs/2); % normalized stopband interval Rp = 3; % 3-dB attenuation at passband Rs = 30; % 30-dB attenuation at stopband [n,Wn] = buttord(Wp,Ws,Rp,Rs); % Butterworth filter [b,a] = butter(n,Wn); bandNoise = filter(b,a,Noise); % Band-limiting the noise Note: this example is extracted from **broken link removed** with some modifications and additional comments.
