Theory for pre emphasis and de emphasis

Webb27 juni 2024 · Pre-emphasis comes in two flavors: pre-shoot and de-emphasis. Transmit pre-emphasis is technically not equalization, but it has the same goal of reducing the … 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.
