Abstract:
A digital data acquisition system for receiving an analog input signal comprising a plurality of octavely-nested components including a base octave and a selected number of higher-level octaves, and for transmitting digital data words representative of each component over a channel, the system comprising:a data transmission controller for generating transmission strobe signals defining a series of octave transmission cycles each associated with one of said octaves, each octave transmission cycle having a series of octave strobe states including at least one octave strobe state associated with the base octave and a successively higher numbers of octave strobe states associated with successively higher-level octaves, the transmission strobe states associated with each octave being uniformly distributed during each octave transmission cycle, the data transmission controller generating during each octave strobe state transmission strobe signals identifying an octave associated with said octave strobe state; andan interface for receiving the analog input signal and generating digital words in response thereto for each of the octavely-nested components, the interface transmitting the digital words over said channel for a component corresponding to an octave identified by the transmission strobe signals from the data transmission controller.
