DIGITAL SIGNAL FILTERING METHOD AND DEVICE REALIZING SAID SIGNAL Russian patent published in 2021 - IPC H03H17/06 

FIELD: radio equipment.

SUBSTANCE: device includes N-1 series-connected delay elements, where N>1, input of the first delay element is signal input of device, N inputs of samples pulse characteristic of device, N multipliers, which first inputs are connected to corresponding inputs of pulse characteristic readings, and adder to N inputs, output of which is output of device, input of input coefficient of counts of pulse characteristic, connected simultaneously with second inputs of multipliers, N units of crossing with two inputs and one output each, connected by outputs to corresponding inputs of adder, first inputs of crossing units are connected to corresponding outputs of multipliers, second inputs of crossing units, starting from the first unit, are connected to corresponding outputs of delay elements, starting from the first element, and the second input of the zero intersection unit is connected to the signal input of the device. At that, each intersection unit includes the first adder with the first forward and second inverse inputs, second adder with first and second direct inputs and third adder with first inverse and second direct inputs, first and second computer of module, wherein first and second adder first inputs are first intersection unit input, second inputs of first and second adder are second input of intersection unit, outputs of the first and second adder are connected to the first and second inputs of the third adder through the first and second calculators of the module respectively, the output of the third adder is the output of the intersection unit.

EFFECT: technical result consists in broader functional capabilities of digital filtering of signals, providing possibility of limiting amplitude of output signal without spreading spectrum.
