EE Signals problem...HELP

[AznMaverick]

if i have a signal x(t)=sin(2*pi*t), 0<=t<=3, and

h(t)=e^-(t) for 0<t<=2, and 0 otherwise

how do i find the output, y(t)?

i tried to find H(jw)=which i got to be -e^(-2-2jw)+1/1+jw, and ak to be 1/2j -1/2j for k=3 and -3, and ak=0 for k!=3 and -3. now what do i do?

Why is the transfer function's time not defined for 0<=t?

You have to do a graphical convolution. It's not easy to explain in words but examples should be in your textbook.

transfer function is 0 at all places other than 0<t<=2

by the way, we are using fourier series

 

[HomerSapien]

were you given a circuit to go with it or is it just the function.

If you just have the function, use mathematica, maple, or matlab to plot it. Or even a ti-89.

set the horzontal axes as 0-3 and that should do it. Im assuming it is asking for the output in volts.

only the function is given, and they want an output function using fourier series.
