Question

The auto correlation Rxx(t1 = 0.5T, t2 = 0.7T) will be

(a) 1

(b) 0

(c) A x A

(d) 0.5 (A x A)

I have been asked this question at a job interview.

I'd like to ask this question from Random Process in chapter EDC Overview of Electronic Devices & Circuits

Answer 1

Right choice is (c) A x A

The explanation is: Here Rxx is AxA if both t1 and t2 are different and zero if they are same. Hence the answer is AxA.
