5.2.3.4 Analog Anti-Aliasing Low Pass Filter
The 7th order equal-ripple analog filter p rovides 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 eq ualized by
the FIR to the NPV target response for Viterbi detection. The FIR filter consists of 10 indep endent
programmable taps.
