hi,

I read about convolution and the popular examples of rectangular pulses and exponentials with square functions but

unfortunately I did not find any help on convolving two exponential functions.

I need to convolve: $\displaystyle x(t) = e^{2t} [u(t-1)-u(t-4)]$ and $\displaystyle x(t) = 2e^{-t} [u(t+1)-u(t-5)]$

Is the solution much different from the rectangular pulses derivation?

I sketched each signal to identify the t 'limits' of each one due to the unit steps. What is the closed form solution exactly?

I would really appreciate any guidance thanks.
