Thermistor is certainly not binary but a transistor can operate either in the digital or analog domain. So d seems the best answer if only one answer is correct.Question:
Which device is not binary in nature?
From what I can figure going though my books is the answer is D Thermistor can someone verify my answer.
This was a silly question, as a transistor can operate in a saturated mode and act as logic device in such case, remember TTL?A and D.
A transistor is clearly analogue in nature and so is a thermistor. A switch and relay (same thing really) are both digital-only.
A lot of teachers know absolutely nothing about electronics, so it's not surprising - the number of questions you get which have no actual answer (or more than one answer) has always been a problem.I have always hated questions like these. Where the prof thinks he is so friggin clever but in reality his question just plain sucks. There's no way you can claim that a transistor is by nature binary.
