Re: Poles and zeros
I was just reading this discussion and could not get some points:
I can understand how zero comes into picture. We say that there are two parallel paths from input to output and from these two paths, signal from input to output reaches in opposite phase, so they cancel each other and we get a zero there.
Can someone explain the effect of pole also in the similar manner. Why do we say that signal is infinite at pole frequency?
Added after 14 minutes:
I don't agree by saying that
'i was thinking that, a path between i/p & o/p, that means the i/p short with o/p. so, o/p voltage = i/p voltage. does that give me a zero? '
i/p is not shorted to o/p (in that case, transfer function is 1), o/p is shorted to ground (so the transfer function is 0)
