A New Method of Amplifying with High Efficiency a Carrier Wave Modulated in Amplitude by a Voice Wave

This paper describes a new high-efficiency amplifier circuit with a quantitative analysis of its operation. This circuit operates by dividing the wave in several sections, amplifying each section separately and recombining the sections in the output to produce a larger wave of the original form. The circuit has special application to controlled-carrier systems and relatively high efficiencies are obtained, the companson with conventional arrangements being most favorable at low modulation levels.
