Electronic circuit for connection to inductive devices - uses negative input and output resistance to compensate for DC resistance

摘要

Control is achieved by an equivalent negative output resistance equal to the dc resistance of the device. Pref the negative output resistance is variable, automatically adjusting to equal the dc resistance of the output device, e.g. a loudspeaker. A negative input resistance corresponds to the dc resistance of a signal sound e.g. a microphone. USE/ADVANTAGE - Audio circuit esp microphone, loudspeakers, headphones. Reduced distortion.
