A breadboarded circuit design using a BCD-to-decimal decoder has a problem wherein the operation of the system is erratic. The technician uses his scope to examine the waveforms throughout the system and doesn't really see any problems. While he's scratching his head, what helpful advice can you offer him as to what might be wrong and what to do to correct the problem? Select one: Oa. There is probably a bad connection on the wire wrap proto board; recheck the wiring. Ob. The decoder is thermally intermittent; replace it. Oc. Glitches are probably the culprit; strobe the decoder. Od. Either A or B is correct.
