FREQUENCY AGILE DIGITAL COMPUTATIONAL SYNTHESISER Russian patent published in 2013 - IPC H03B19/00 H03L7/18 

FIELD: radio engineering, communication.

SUBSTANCE: digital computational synthesiser has a reference generator 1 and a formation and delay unit 2, a first memory register 3, a first counter 4, a code multiplier 5, a digital storage 6, a code converter 7, a digital-to-analogue converter (DAC) 8, a low-pass filter 9, the output of which is the analogue output of the digital computational synthesiser; a second memory register 10, a second counter 11, a third memory register 12, a variable-ratio divider 13; inputs of the first, second and third memory registers are the digital inputs of the digital computational synthesiser.

EFFECT: high rate of adjusting operational frequency.
