Direct digital frequency synthesizer with a combined method of synthesis output harmonic signal

摘要

Principles of construction of the direct digital frequency synthesizers was proposed. The proposed structure of the phase synthesizer accumulators based on Galois adders that will increase the bit synthesis and improve their frequency response range expansion in the direction of the synthesized signals. We consider a combined method of synthesis a harmonic signal on the basis of the Taylor series approximation and CORDIC method.
