I'm trying to simulate pulse transmitted through bandpass filter (actually ,it is APD that has band pass type frequency response)
One of the problem is that the frequency respons is not like a typical band pass filter.
It is like a high-pass filter for low frequency and,like a low-pass filter
for high frequency.
I don't know how to get the
transfer function of such a filter,
Can I just multiply transfer funtions of two-filters?
