Abstract
PURPOSE:To prevent a waste of electric current by checking a combination of input bits and then by treating it not as an input to a circuit when the combination does not relate to the output of the digital circuit. CONSTITUTION:When input bits x1, x2, x3, and x4 and phi, 1, 1, and 1 respectively and the output shows ''don't care'', inputting the combination of those inputs holds output 14 at 1 to open the gate of a circuit connected to the next stage, so that it will not be regarded as an input to the circuit.
