What is a Crossover Network?

A Crossover Network is a network that filters and diverts signals to different sections of a circuit.

A crossover network may separate different input signals based on their frequency, sending low frequencies to one side of the circuit and high frequency signals to another part of the circuit.

For example, a speaker crossover network filters out the various input sound signals and filters them by frequency. It sends low frequency signals to the woofer speakers, mid frequencies to the midrange speaker, and high frequencies to the tweeter speakers.

This is a speaker crossover network:

The idea of a crossover network again is that it separates the input signals , filtering them, and sends the separated, filtered signals to their respective parts.
