I need a help in solving this convolution. Anybody has any idea? i don't know how to integrate a function multiplied with delta function and a delay function as attached.
Thank you

When you convolve two CT signals, one being a regular input function f(x) and another being the delta function... the convolution f(x) * delta(x) = f(x).

Similarly, f(x) * -delta(x) = -f(x)

I can't open your attachment just yet.
