Застосування двотактних підсилювачів постійного струму у прямому цифровому синтезі

Abstract

Application of push-pull DC amplifiers DC in direct digital synthesis of analog signals was suggested. A structural diagram of the device push-pull DC amplifier in DDS instead of low-pass filter was proposed. It is shown that such use of the push-pull DC amplifiers allows flexibility to adjust the amplitude of the output signal, and harmonic content is low enough in wide frequency range.
