Question

Laboratory Work Write a MATLAB code segment that will plot two periods of the continuous-time signal x()=4.0cos(200 )+2.0cos(500 -()/(2). Use a time interval of 0.1ms; this corresponds

A) t = 0:0.0001:0.004;
x = 4co(200) + 2co(500 - /2)
plot(t, x);
B) t = 0:0.0001:0.002;
x = 4co(200) + 2co(500 - /2);
plot(t, x);
C) t = 0:0.001:0.002;
x = 4co(200) + 2co(500 - /2);
plot(t, x);
D) t = 0:0.001:0.004;
x = 4co(200) + 2co(500 - /2);
plot(t, x);
