Dear Frogpad, thank you for the reply. As far as i know if x(t)\delta(t) , the answer is x(t) at t=0, i.e x(0). isn't it? So, do we need to consider x(0) as a constant convolve with z(t) then? it doesn't seem right to me. zai

Thank you for the reply. For this particular property i knew it already. my question is if f(t)=[x(t).y(t)]*z(t) and y(t) is a delta function. How do i solve this problem? Zai

for linear time invariant system, y(t)=h(t)*x(t) where y(t) is the output , x(t) is the input and h(t) is the impulse response.(* is the convolution) The definition of convolution is y(t)=integration from -infinity to +infinity (h(tau)x(t-tau)d(tau) p/s: i don't know how to use...

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
