DIGITAL FREQUENCY SYNTHESIZER Russian patent published in 1995 - IPC

FIELD: pulse equipment. SUBSTANCE: digital frequency synthesizer is intended for formers of multifrequency signals with constant or changing spectral composition. It includes wires 1=1, 1=2,... 1=N of codes of synthesized frequencies, digital integrators 2=1, 2=2,...2=N, reference generator 3, code converters 4=1, 4=2,...4=N, coder adder 5 with N information inputs, digital-to-analog converter 6, low-pass filter 7 and output signal wire 8. EFFECT: frequency range of output signals expanded to higher frequencies with provision for independence of maximum synthesized frequency of number of frequencies in output multifrequency signal. 3 cl, 3 dwg
