PAM-4 Decoding & Timing Jitter Simulator
0% Offset
25 dB
DECODED SYMBOLS (2 BITS PER DURATION)
Summary: In PAM-4, the receiver uses 3 thresholds to distinguish between 4 levels.
If Timing Jitter is high, the "Yellow Sticks" move away from the stable center of the pulse, causing the receiver to sample the "Transition Edge" instead of the "Pulse Peak," leading to errors.
