In which waveform logic 1 is represented by equal amplitude alternating pulses?

(a) Unipolar RZ

(b) Bipolar RZ

(c) RZ-AMI

(d) Manchester coding

This question was addressed to me by my school principal while I was bunking the class.

My question is taken from Baseband Transmission in portion Formatting and Baseband Modulation of Digital Communications

Best answer
Right choice is (c) RZ-AMI

Best explanation: In RZ-AMI logic 1 is represented by equal amplitude alternating pulses and logic 0 is represented by the absence of a pulse.
