I have this fsk function code:
function [x]=fsk_encode(b,s,f0,f1,N,Fs,K)
% b= bit sequence vector
% s(1)= output level for 0
% s(2)= output level for 1
% N= length of bit sequence
% Fs= Sampling frequency
y=zeros(1,N*K); %Setup output vector
%for each bit calculatee the rando samples
for n=1:N
for k=1:K
t = (k - 1) / Fs;
if(b(n)==0)
y((n-1)*K+k)=cos(2*pi*f0*t); % pulse=0
else
y((n-1)*K+k)=cos(2*pi*f1*t); % pulse=1
end
end
x=y; %set output
end
And this is another code that calls the function in order to get the power density spectrum:
clc;clear;
% EE 382 Communication Systems- Lab 8
% Plots the power spectrum of the ASK modulation
% First specify some parameters
N=256; % number of bits per realization

T=0.001; % bit duration in seconds
delf =2e+3;
fc=10e+3;
f0=fc-delf;
f1=fc+delf;
Fs=8*f1; % sampling frequency (this is needed to calibrate the frequency axis)
K=(T/(1/Fs));

- For a band-rejection filter, the response drops below this half power point at two locations as visualised in Figure 7, we need to find these frequencies. Let's call the lower frequency-3dB point as fr and the higher frequency -3dB point fH. We can then find out the bandwidth as f=fHfL, as illustrated in Figure 7. 0dB Af -3 dB Figure 7.
