Hey trojsi.
Did you try and setup the convolution integral directly and just use that to evaluate the actual integral? Are you just trying to find the convolution or the frequencies for something like a Laplace Transform?
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: and
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.

I need to understand how to decide which limits to take for the integral. Attached find my sketches till now.Attachment 25465
The standard convolution operation has limits from 0 to t. If your signal is 0 in particular regions, just split up the integral to get the non-zero parts and note where the limits are, but to start off with, your standard convolution integral of two general functions (or signals) is Integral (0 to t) f(t-u)g(u)du or Integral (0 to t) g(t-u)f(u)du.
If the signal is largely missing across chunks of the real line, then just remember that Integral (a to c) = Integral (a to b) + Integral (b to c) where a < b < c and if one region is zero then it can disappear.
