Question

The primary advantage of this method is

(a) redistribution of spectral density

(b) to favor low frequencies

(c) redistribution of spectral density & to favor low frequencies

(d) none of the mentioned

I had been asked this question during an interview.

Question is from Correlative Coding in portion Formatting and Baseband Modulation of Digital Communications

Answer 1

Correct option is (c) redistribution of spectral density & to favor low frequencies

Best explanation: Each bit can be independently detected in-spite of strong correlation and this provides redistribution of spectral density and also favors low frequencies.
