Abstract:
1. A feed forward equalizer for analog equalization of a data signal received over a data transmission channel comprising: (a) a Master Delay Locked Loop for generating equidistant reference phase signals; (b) a Slave Delay Line formed by serial connected Slave Delay Units, wherein each Slave Delay Unit has a Slave Delay Element to delay the received data signal with a predetermined delay time and an analog amplifier which amplifies the delayed output signal of the Slave Delay Element with a respective weighting coefficient to generate a weighted delay signal, wherein the analog amplifier is switched transparent in response to a corresponding reference phase signal generated by said Master Delay Locked Loop; and (c) subtracting means for subtracting the weighted delay signals which are selected by means of a multiplexer from the received data signal to generate an equalized output data signal.
