Abstract
A data stream to be transmitted is received by a digital interface (52) and converted into a frequency encoded data. A gains block (54) receives the frequency encoded data and a gain adjustment signal, and produces a gain adjusted data to compensate for undesirable system level passband gain variation. The gain adjusted data is converted to a time domain data. The time domain data is processed by a high-pass and a droop correction filter (58, 59) to produce a filtered data. The filtered data is provided through an analog front-end (60) in order to provide a filtered analog data.
