function x = generate_pulse(amplitude, frequency, phase, fs, duration, duty)
% GENERATE_puse: returns a matrix of sampled pulse wave
% CONTRIBUTORS:
% Brian Tran: Created the wave
% DOCUMENTATION:
% phase shift is in number of periods
% fs is the sampling frequency: how many sample points per second
% duration is time in seconds
% duty is a number between 0 and 1
% initialize local variables from input arguments
n = fs * duration; % number of samples (length of matrix)
dt = 1 / fs; % sampling period: time between two sample points
% initialize a one dimensional zero matrix to be populated
x = zeros(1, n);
f0=1e+6; % 1MHz
Fs=3e+6;
Tf=0.001; % 1 millisecond
t=0:1/Fs:Tf-1/Fs;
td=0.1; % duty cycle
A0=10; % 10 Volts
F=0;
N=1000; % Number of points
% populate the matrix
for n = 1:N
F=F+(1/n)*cos(n*2*pi*f0*t).*sin(n*pi*td);
end
F=F*(2*A0/pi);
F=F+A0*td;
