Which of the following is not a characteristic of PN sequence?

(a) Nearly equal number of 0s and1s

(b) Low correlation between shifted version of sequence

(c) Non deterministic

(d) Low cross-correlation between any two sequences

This question was posed to me in an interview for job.

My question comes from Spread Spectrum Modulation Techniques topic in chapter Modulation Techniques for Mobile Radio of Wireless/Mobile

Best answer
The correct choice is (c) Non deterministic

Best explanation: Pseudo-Noise sequences are deterministic in nature. Certain characteristics of PN sequence are nearly equal number of 0s and 1s, very low correlation between shifted versions of the sequence, very low cross correlation between any two sequences.
