Title:
SIGNAL PROCESSOR
Document Type and Number:
Japanese Patent JP3338713
Kind Code:
B2
Abstract:

PURPOSE: To improve the generality of this signal processor by non-linearly changing the density of output signal pulses in a forward process against that of input signal pulses in simple digital logic constitution for processing a signal expressed by a pulse string.
CONSTITUTION: A signal processing means has an AND operation means for operating AND between an input signal expressed by a pulse string and a connection coefficient expressed by a pulse string, a grouping means for grouping the operation result of the AND operation means into plural groups, OR operation means 33a, 33b for operating OR between operation results in each group, a logical operation means 34 for executing the logical operation of operation results from the means 33a, 33b, pulse density changing means 47, 48 for changing the pulse density of a pulse string outputted from the means 34, and a connection coefficiency changing means for changing the connection coefficiency based upon an error signal expressed by pulse density.
