I am given this:
sampFreq = 15000; % sampling frequency, this value should be over twice the largest frequency comp, of signals
T = 1/sampFreq;
t = 0:T:2; % sampling time
%st variables
a_s = 1; % amplitude
f_s = 60; % frequency
ph_s = pi; % phase angle
c_s = 1; % constant off set
st = my_sin(t,a_s,f_s,ph_s,c_s);
figure(1);clf
subplot(2,1,1);plot(t,st,'b');
xlabel('Time (sec)');
ylabel('Amplitude');
title('Data Signal')
xlim([min(t),max(t)]);
ylim([min(st),max(st)])
adjfig();

I cannot give you the exact code because its a homework assignment. But this should lead you towards the answer.
So the signal s(t) is the sinusoidal signal which you have been given. You are told to construct another signal f(t) which should be a square wave with the given parameters.
You can use the function "square" (check the documentation) or alternatively you can generate a random stream of binary bits using randi([0,1],x,y) and sample it using your sampling frequency.
Best of Luck!
