A digital computing synthesizer with a V-shaped frequency change law
I. V. Ryabov · Instruments and Experimental Techniques · 2006
The structure of a digital synthesizer based on direct digital frequency synthesis is described. The synthesizer can operate in the frequency band of 0–10 MHz with a frequency step of <0.005 Hz, the phase noise level is less than −140 dB/Hz, and the amplitude noise level is less than −60 dB/V.
