zobelBoucherotnätverk

A zobelBoucherot network is a type of electrical circuit used to cancel out or minimize unwanted electromagnetic interference (EMI) in power supply lines. It is named after its inventors, Georges Boucherot and Otto Zobel, who developed these circuits in the early 20th century. The core principle behind a zobelBoucherot network is to create a path that bypasses the intended load for high-frequency noise.

Typically, a zobelBoucherot network consists of a resistor and a capacitor in series, connected in parallel with the load. This RC combination is designed to have an impedance that is low at high frequencies, effectively shunting noise away from the sensitive equipment. The resistor is often chosen to match the characteristic impedance of the transmission line, helping to absorb the noise rather than reflecting it. A small inductor may also be incorporated in some designs to further improve noise suppression at specific frequencies.

These networks are commonly found in audio amplifiers and other sensitive electronic devices where preventing noise from entering the power supply can significantly improve performance and sound quality. By effectively filtering out unwanted high-frequency signals, zobelBoucherot networks contribute to a cleaner and more stable power source for the main circuitry.
