It depends on what you are amplifying. But most of the time you're amplifying a signal that is too weak. For example when you are amplifying an electric guitar, the guitar itself generates a very...
To get all the audio voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is at...
The purpose of impedance matching is to provide for the highest efficiency between either the stages of an amplifier circuit or from a device to the amplifier for the same purpose. Impedance matching...
