Graph Simple Pulse function in matlab HELPPPPPPPPPPPPP PLEASE
显示 更早的评论
Consider a pulse function of time duration 0 to T which is half of a sine wave:
x(t) = 0 t < 0
x(t) = Asin(pi*t/T) 0 < t < T
x(t) = 0 t > T
Calculate the Fourier transform of this pulse. For A=1 and T=1 (sec) plot the magnitude of X(f) versus f.
*I just need the matlab code. Thank you****

Just the MATLAB code? You mean we can skip the comments and the descriptions of what we are doing and you promise not to ask questions about how it works?

Just the MATLAB code.
f = linspace(-50,50,301);
t1 = pi .^ 2;
t4 = -pi - (2 .* f);
t5 = exp((-1*i) .* t4);
t12 = exp((i) .* (f + pi ./ 0.2e1));
t17 = sqrt((0.2e1 .* t1) + t1 ./ t12 .* ((i) + (-1*i) .* t5));
t18 = f .^ 2;
t20 = abs(-0.2e1 .* t1 + (2 .* t18));
t23 = 2 ./ t20 .* t17;
plot(f, t23);

Perhaps the OP does not ask for details. I promise, I will not ask, too.
Btw, the code works well, if you rename all "t4" to "t2".

The calculation was a bit on the Heavy Side.
