In which waveform logic 1 is represented by equal amplitude alternatin

1.	In which waveform logic 1 is represented by equal amplitude alternating pulses?(a) Unipolar RZ(b) Bipolar RZ(c) RZ-AMI(d) Manchester codingThis 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
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.
