The CCD signal processor includes all the necessary circuitry to perform three-channel
conditioning and sampling. The signal chain consists of three-channel correlated double
sampling (CDS) and programmable gain adjustment of the CCD output (PGA) is a 10 bit
analog to digital connector (ADC) quantizes the analog signal.
