Thank you all for your help :)

Sadly, yes. I must convolve... Will there be any advantages of taking FIR approximation of IIR filters?

Thank you for your reply and sorry for keep asking... The equation I'm dealing with contains a convolution, like A = f*B, where B is the input signal and f is the impulse response of a filter. Does this mean that I am forced to use FIR filtering and no Butterworth or Chebyshev for me...

Can I ask one more question? If I have a low pass filter, whose transfer function is H(s) = a/(a+s), It it an IIR filter or FIR filter?

Thank you for your reply :)

Hi all.. I'm a new to filters and I need some help understanding filters (I'm in mechanical engineering) So far, I've found out that FIR filters use convolution and has a finite impulse response. On the other hand, IIR filters are recursive and have an infinite impulse response. But...
