General-purpose data acquisition boards are required to be customized for both local ADC related functions (ADC hardware interface, clock generation, sample and hold signals, etc.) as well as application related functions (pacing, acquired signal filtering, gain and offset processing, etc.) on a per-channel basis. Additionally, these boards are required to interface to various digital control functions as determined by the application.
