Question

Minimum viewing angle of resolution of human eye is ________

(a) \(\frac{ʎ}{d}\)

(b) \(\frac{1.22ʎ}{d}\)

(c) \(\frac{3ʎ}{d}\)

(d) \(\frac{2ʎ}{d}\)

I have been asked this question in an internship interview.

The above asked question is from Problems of DSBSC in portion Double Sideband Suppressed Carrier Modulation of Analog Communications

Answer 1

The correct answer is (b) \(\frac{1.22ʎ}{d}\)

The explanation is: Minimum resolution of human eye for clear observation is generally \(\frac{1.22ʎ}{d}\). The diameter of human eye is about 25mm.
