Low- pas filters are electronicc obvods that allow signals with frequencies below a certain cutoff point to pass treamgh while attenuating higher frequencies. They are widely used in audio procesing, commulation systems, and signal conditioning to reduce noise and imprope signal quality.

Principles of Low- pas Filter Design

Te currental principla of a low-pas filter is to block high- currency signals while pasing low -currency signals. This is achied treachh reactive contrients such as resistory, capacitors, and inductors. Te cutoff currency determinates the point where te filter injours to attenuate signals.
