34. N-Path Filters: Part1 – Architecture

“This video introduces the N-path filter and explains its working principle using the LO-switched
mixing and baseband filtering. It shows how two mixers driven by the LO, with a low-pass filter,
effectively create a band-pass filter whose center frequency is set by the LO.
The lecture walks through the basic architecture and then presents a
simplified version to build intuition on how the filtering action is achieved.”
