Why does the high pass filter have a zero but the low pass doesn't?
What do zeroes do in the distance method?
Can a pole be reached for a low or high pass filter? How can
?
Why do we use
instead of
?
What constitutes the two filters ``seeing'' each other?
How does a buffer make the second segment of sequential filters not draw any current?
Do buffers contribute any other internal impedance?
What are sequential low-pass filters used for?
If you have multiple sequential filters, can you just keep multiplying
as long as you have a buffer between each one?
How do sequential filters behave if the second section does draw non-negligible current?
There seem to be a lot of approximations with filters. How sharp can the actual ``passing'' zones be made?
Is the sole purpose of a buffer enabling us to use the multiplication rule? Will it affect the circuit in other ways?
