WebOct 1, 2012 · Overview of PAM-2, PAM-4, and duobinary signaling. Fig. 2 compares random data eye diagrams and frequency spectrums for the three common modulation formats. PAM-2 or binary signaling is the simplest to implement at both the transmitter … Webless than about 39 dB loss at 13 GHz. Above this attenuation PAM4 looks better. Unfortunately for the Backplanes where PAM4 has an advantage, the SNR for both codings seems to be insufficient for BER= . So it seems that the copper does not prefer PAM4. However the silicon may work better at the lower data rate that PAM4 allows. 10−12
