A Zobel is an impedance matching circuit often used with loudspeakers. A Zobel circuit is also known as a Boucherot cell or somewhat incorrectly as an RC snubber. The nominal impedance of a ...
Here this circuit is based on the principle of audio amplification using operational amplifier and pulse width modulation using 555 Timer. In this article we are describing the principle, design and ...
Two of the most often used amplifier building blocks in audio amplifier design are the common emitter amplifier with emitter degeneration and the emitter follower using the same circuit biasing. The ...
