I can't seem to figure out how to get past this. Any help is appreciated,
I'm not sure what other result you are expecting. The loop is obiously running to completion since t = 1. On the last iteration of the loop: g2=A*cos(2*pi*fc*t+theta) g1=A*cos(2*pi*fc*(tTa)+theta) and since A=10, t = 1, and theta = 0 g1 = g2 = 10 because fc*(tTa) = 1000*(.94) = 940 and cos(2*pi*n) = 1 for any interger n.
