Splet18. mar. 2014 · Pre-emphasis shapes a signal before it is sent and post-emphasis shapes it after it is received. The idea is to compensate for distortions that the transmission channel may/will introduce. Radars also sometimes use this to spread a pulse and thus transmit more power. Then on reception compress the pulse to improve range resolution.

In PCI Express Gen 2 signaling, the data being transmitted is 8B/10B encoded and signaling is non-return-to-zero (NRZ). The run-length limitation of 8B/10B encoding guarantees a low-frequency of 500 MHz for data signals. The NRZ signaling guarantees the fundamental frequency of data signals will be 2.5 GHz.
