SIGNAL CONVOLUTION DEVICE Russian patent published in 2006 - IPC H03H17/06 

FIELD: radio electronics; linear permanent-parameter difference circuits.

SUBSTANCE: proposed signal convolution device that can be used, for instance, to construct electronic analog filters of desired phase-frequency response characteristic close to ideal one has elementary phase circuits, proportional sections, and adders; elementary phase circuits are integrated into three groups incorporating equal number of elementary phase circuits. Picked off output of first group is input signal delayed copy. Two-input adders are inserted between elementary phase circuits of two other series-connected groups. Each adder is connected through one of its inputs to output of respective proportional section. Inputs of all proportional sections whose gain depends on synthesized difference circuit characteristic turned over from left to right are integrated and connected to input of first group of elementary phase circuits to form input signal bus. Output signal is picked off last adder.

EFFECT: enhanced speed and ability of implementing real-time convolution operation.
