Abstract

PURPOSE:To decide plural conditions at a time and with a simple circuit by using a memory which has an address input of the same number of bits as those of an input signal and delivers the data of >=1 bit. CONSTITUTION:An input signal 10 contains 4 bits, and a memory 1 has 16 addresses (=2<4>) with constitution of (16 addresses X 3 bits). For instance, the signal 10 has a bit pattern of 1001. In such a case, a deciding signal 11 is set at 0. While a deciding signal 12 is set at 1 when the signal 10 has bit patterns of 0000, 0010 and 1100. The signal 12 is set at 0 with other bit patterns. In addition, a deciding signal 13 is set at 1 when the bit patterns of the signal 10 are included within a range of 0010-1000. Otherwise, the signal 13 is set at 0. If these working conditions are set previously, the memory 1 uses the signal 10 as an address and delivers the contents of bits 1-3 in the form of deciding signals 11-13.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention provides a method for simultaneously determining whether a human input signal matches a preset bit butter 7, or is within or outside a preset range. The respective article (
This relates to a signal determination circuit that outputs a determination signal corresponding to 'l.

(b) Prior art and problems Conventional signal determination circuits include those that use comparators and those that use memory.
If the conditions are to be judged at the same time, as many judgment circuits as there are conditions are required, resulting in the need for multiple circuits.

(C) Aspect 1 of the Invention This invention is based on a plurality of bits. +I human power signal or one type or more set in advance -L bit butter 7
This is about a nine-signal circuit that determines whether the signal matches any of the conditions, or whether it is within a preset range.
The purpose of this invention is to provide an A5 bow determination circuit that can determine 'l.

(c) Embodiment of the Invention First, FIG. 1 shows a power diagram of an embodiment of the invention.

10 in FIG. 1 is a human input signal, and 1121 is a 4-bit (111ν) human input signal-J.

Memory l is manually operated (,i, bow 10 is at address f1:t,)'rusui1. t；te finger】1・shikon f'i J
The contents of Pino 11, Bi, Nodo 2, and Pino 173 are expressed and output as 11 to 13, respectively.

Since the number 1.5;10 consists of 4 pins l-R1, memory 1 uses 2'=I(mail with address i).

In this embodiment, a memory (3 addresses x 33 hits) is used.

Next, as a specific example, a method for setting the contents of each address in the memory 1, such as the movement f'1 in FIG. 1, will be explained.

As a specific example, consider next the case of the small condition.

('/) Human power signal 10 bit butter/karoolo
When included in the range from J to rl, 000J, the judgment signal 13 is set to "1". If it is not within this range, the determination signal 13 is set to "0".
