Abstract
Abstract The present application relates to electronic circuitry for the improved handling of electric signals, particularly to the amplification thereof. The present application discloses an integral-amplifier that has a much higher efficiency than corresponding prior-art circuits, and also discloses that, where so desired, intermodulation signals may be reduced to a negligible value.
