ABSTRACT:
A digital signal process of a plurality of functions is enabled by a common hardware constructed on one chip having input terminals t1, t2 and t2'; output terminals t3 and t4; and a control signal input terminal t5. The chip is constructed to include class sorting circuits 111a and 111b; delay and selecting circuits 112a and 112b; switching circuits 113a and 113b; switching circuits 114a and 114b; coefficient memories 115a and 115b; filter operating circuits 116a and 116b; a line delay circuit 117; a product sum operating circuit 118; and a switching circuit 119. Signal flow and circuit functions are selectively controlled by control signals. The functions of the chip can be consequently switched and a plurality of signal processes are realized by one chip.
