Question

Which among the following is not an action carried out in image formation?

(a) Analog to digital conversion

(b) Digital to analog conversion

(c) Conversion of photon into electron

(d) Conversion of signal charge to electrical signal

I have been asked this question in an internship interview.

The above asked question is from Location Awareness topic in portion Location and Environment Awareness in Cognitive Radio of Cognitive Radio

Answer 1

The correct answer is:

(b) Digital to analog conversion

In image formation, actions typically involve processes that convert analog signals to digital form (like analog to digital conversion), convert photon energy into electronic signals (like conversion of photon into electron), or convert signal charge to an electrical signal. Digital to analog conversion, however, is not typically a part of the image formation process itself, as this pertains more to signal output or display rather than the image capturing or processing.
