Test bit pattern generator for pattern recognition machines

摘要: The scanner of the pattern recognition machine scans a pre-printed document containing number patterns which correspond to test bits be produced. There are two distinguishing produce binary one and zero bits. printed in sequence dictated by desired bit pattern. resulting forming applied logics. also carries set which, when scanned, identifying This identification is compared with produced An equal comparison indicates that logics functioning properly. error condition causes displayed. operator or maintenance man can read display determine should probed find error.
