What is cascading?

[ayayay!]

I realized today when looking at a schem that I couldn't give a name to what I was looking at.  Confused?

Anyway, for example, the outputs of ROGs Thundercheif or Matchbox where there's a R then C to ground, followed by an identical R then C to grd.  Is that cascading?

The three J201's in a line are all cascaded, because their drains are connected to the next one's gate. The output of each stage goes into another similar stage.


The RC filters at the output are cascaded. Usually when you have filters, each stage is a "pole". So that RC network at the end is a two-pole RC lo-pass filter.


Cascading: Using multiples of the same/similar circuit in series to gradually add together their effects. I think thats a good definition?

Thanks JKowalski!
