An output gate is connected to four input gates; the circuit does not function. Preliminary tests with the DMM indicate that the power is applied; scope tests show that the primary input gate has a pulsing signal, while the interconnecting node has no signal. The four load gates are all on different ICs. Which instrument will best help isolate the problem?

Digital logic is the underlying logic system that drives electronic circuit board design. Digital logic manipulates of binary values through printed circuit board technology that uses circuits and logic gates to construct the implementation of computer operations.
