Abstract

This circuit provides appropriate signals to indicate the presence of more than one bit or the presence of more than two bits. The signals are used to turn on a double error latch. A group of five AND devices develops the "more-than-two-bits" signal while another group of five AND devices develops the "more-than-one-bit" signal.

Logical Validity Check Circuit

This circuit provides appropriate signals to indicate the presence of more than one bit or the presence of more than two bits. The signals are used to turn on a double error latch. A group of five AND devices develops the "more-than- two-bits" signal while another group of five AND devices develops the "more- than-one-bit" signal.

In addition, the circuit provides for tube component failures in the latch to turn the latter on as a result of such tube failures.
