Re: [PIUG List] Japanese S Number

Hi Cathy,

I think you are looking for following patent:

Patent number:JP6201779A2
Title: TEST CIRCUIT
Assignee: RICOH CO LTD
Abstract: PURPOSE: To quickly carry out the motion check of a transversal
filter by inputting the same operating data into each of a plurality of the
same operation elements, and judging a difference in the result of an
operation carried out through each operation element.
CONSTITUTION: In a transversal filter 502 which has received the data of a
multiplier and a multiplicand from an updown counter, the identity of the
result of computation output from each of multiplying instruments a1 to an
is judged by an EXOR (exclusive OR) gate provided in a comparator e1. When
all of the results of computations input from each multiplying instrument
are the same, the comparator e1 outputs a low level signal, and when the
above result of computation is not the same, the comparator e1 outputs a
high level signal. A signal output from the comparator e1 is input into F/F,
and in the case where the signal is a high level, LED is radiated.
