I'm having trouble understanding convolution. In particular, in convolving h(t) and x(t), I have no idea what to do when x(t) = u(t-1). So for example, if h(t) = exp(-at)u(t) an x(t) = u(t-1). Is this even the right set up? I don't think it is.(adsbygoogle = window.adsbygoogle || []).push({});

[tex]\int_o^t e^{-a(t-T)}u(t-1)dT[/tex]

the other idea I had was

[tex]\int_1^t e^{-a(t-T)}u(t)dT[/tex]

but I doubt this too.

Help?
