Web21 de jul. de 2024 · Comparison of PAM4 vs. NRZ. In a nutshell, NRZ is a modulation technique with two voltage levels to represent logic 0 and logic 1. The voltage literally does not “return to zero”; logic 0 is a negative voltage, and logic 1 is a positive voltage. PAM4 uses four voltage levels to represent 4 combinations of 2 bits logic: 11, 10, 01, and 00. WebIn the following sections, we discuss various modulation techniques. We start with OOK, which forms the basic standard for evaluation. 3.1 On-off Keying – Non Return to Zero (NRZ) On-Off-Keying is the simplest form of amplitude-shift keying (ASK) modulation that represents digital data as the presence or absence of a carrier wave.
