FIELD: radio engineering. SUBSTANCE: device has serial circuit of accumulating adder, memory unit, digital-to-analog converter and low-pass filter. Clock and information inputs of accumulating adder are respectively input of reference signal and frequency setting inputs. In addition device has OR gate, and multiplexer, which information inputs serve as frequency setting inputs and additional code setting input of device, which control input and first input of OR gate are connected to carry output of accumulating adder; output of OR gate is connected to clock input of accumulating adder; second input of OR gate serves as input of reference signal of device; information input of multiplexer is connected to information input of accumulating adder. Capacitance of accumulating adder is corrected in each cycle of its operations. EFFECT: increased efficiency of output frequency when capacity of accumulating adder and frequency of reference signal are not factors for one another. 1 dwg |
