The higher frequency in the speech signal is needed to be emphasized in order to undergo further process and it is done in pre-emphasis
If any of the tests fail during compliance testing, users can tap into the DPOJET DisplayPort measurement library for a deeper dive into the failures such as eye diagram mask hit failures and look at the relation between pre-emphasis
The 1MHz I2C interface enables full control of additional functionality such as Signal Detect and Squelch, pre-emphasis
, maskable interrupt generation, internal temperature monitor selection, channel polarity inversion, and output voltage swing with enable.

circuit," in Proceedings of the Optical Fiber Communication Conference and Exposition and the National Fiber Optic Engineers Conference (OFC/NFOEC '2013), JTh2A.
Although there are pre-emphasis
and equalization techniques to recover the eye diagram from a near-closed state, skew poses a unique challenge.
Based on a production-proven silicon platform with a failure-in-time rate well below 10 ppm, the VSC7112 delivers input equalization and output pre-emphasis
enabling 30-dB loss compensation over a 50-inch channel with multiple connectors.
filter, before LPC, may improve the performance.
To achieve 10Gbps data rates, busses will employ signal conditioning techniques such as pre-emphasis
or de-emphasis at the driver and some manner of equalization (like DFE or CTLE) at the receiver.
This is achieved by applying pre-emphasis
to signals on the transmit side to match the loss characteristics of the channel.
The BERTScope is complemented by the DPP125B which adds critical pre-emphasis
to the stressed pattern, and the CR125A that recovers the embedded clock to allow for eye diagram analysis on the resulting signal.
CalDriCon offers a solution not to distort eye diagram at receivers with pre-emphasis
3V, 4-channel, 1:1 DP-to-DP ReDriver supporting automatic pre-emphasis
and output swing regeneration (using Link Training signaling) will sample February 2009, at 250K/yr: $1.
