Pre-Emphasis & De-Emphasis - BrainKart

WebbThe purpose of TX pre-emphasis is to apply delay and inversion to the signal and add it back to the original signal with the proper weight, thereby compensating for ISI from the nearby data symbol. The transmitter equalization requirements for each CEI standard are defined in their respective COM specifications. WebbThe working principle of pre-emphasis is to enhance the high-frequency part of the signal, which just compensates for the high-frequency loss in the cable. The working principle of de-emphasis is to cut off the low-frequency part of the signal, and this may be combined with the increased transmit voltage.
