5.2.3.4 Analog Anti-Aliasing Low Pass Filter
The 7
th
order equal-ripple analog filter provide filtering of the analog signal from AGC before it’s
being converted to digital signal with the ADC. Its main function is to avoid aliasing for the
ADC circuit.
5.2.3.5 Analog to Digital Converter (ADC) and FIR
The output of the analog filter is quantified using a 6 bit FLASH ADC. The digitized data is then
equalized by the FIR to the NPV target response for Viterbi detection. The FIR filter consists of 10
independent programmable taps
