+% 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;
