Why do low and high-pass filters differ so much when they have the same components?
What exactly is an ``integrator'' or a ``differentiator''? Why are they called that?
What are real integrators and differentiators? What do we want them for?
What does
mean?
Why does the low-pass filter act as an integrator?
Since high-pass filters correspond to differentiators, and low-pass filters correspond to integrators, does this imply that a band-pass has no associated function?
At what points do
and
start to deviate from the ideal cases? Are there relatively simple models for these situations? (i.e., when does
become
?) Or when do the phases come into play?
Why does the
of a high-pass filter have a discontinuous jump given a square wave input?
Are the rolloffs in filters always (log) linear? Are there cases where it nees a steeper growth/decay?
