Abstract:

A technique for testing the operability of a binary counter design is described. The six inequalities employed in this technique were derived. These inequalities, the operating equations, described necessary conditions for the transistors to be in the ON and OFF states and the necessary conditions for switching either transistor from the ON to the OFF state. The operating equations formed the basis for a computer program which was written in a manner such that the IBM 704 could predict the probability that a binary counter employing, first 50percent tolerances passive components and second, 20 percent tolerance passive components would operate normally. The results indicate that 50percent tolerance components afford a probability of normal circuit operation equal to 0.919, compared with 1.0 probability for 20-percent tolerance components. Author
