Question

In which waveform one is represented by half bit wide pulse positioned during the first half and zero is represented by half bit wide pulse positioned in the second half?

(a) Bi-p-L

(b) Bi-p-M

(c) Bi-p-S

(d) Delay modulation

I had been asked this question by my school teacher while I was bunking the class.

Origin of the question is Baseband Transmission-2 topic in portion Formatting and Baseband Modulation of Digital Communications

Answer 1

Right answer is (a) Bi-p-L

For explanation I would say: In bi-phase-level one is represented by half bit wide pulse positioned during the first half and zero is represented by half bit wide pulse positioned in the second half.
