Web1.1 NRZ Modulation The traditional method of modulation is called Non-Return to Zero (NRZ) that has two different voltage levels to represent a zero and a one. The voltage level remains constant through the bit interval. The symbol is equal to the bit, and there is one eye in each unit interval. 1.2 PAM-4 WebPAM4 requires half the bandwidth of traditional Non-Return-to-Zero (NRZ) modulation for the same data throughput since NRZ utilizes only two levels, or one bit of information per symbol (0 or 1) [6, 7]. PAM4 has also been shown to suffer less inter-symbol interference (ISI) than NRZ [7]. Eye diagrams for both PAM4 and NRZ modulations can

The PAM4 signal has 1/3 the amplitude of that of a similar NRZ signal. Therefore, the PAM4 signal has a worse Signal-to-Noise Ratio (SNR). Because of the tighter spacing between voltage levels in PAM4 signaling, a PAM4 signal is more susceptible to noise. binary tree vertical order traversalWebA transmission using the NRZ method will have the same baud rate and bit rate because each symbol can contain one bit. For example, a bit rate of 28Gbps (gigabits per second) is similar to a baud rate of 28GBdps (gigabauds per second). While 56Gbps PAM4 will have a line transmission at 28GBdps since PAM4 transmits 2 bits per symbol. binary tree vs heap
