ABSTRACT:
A data acquisition system receives an analog input signal comprising a pllity of octavely-nested components including a base octave and a selected number of higher-level octaves, and transmits digital data words representative of each component over a channel. The data acquisition system includes a data transmission system and an interface. The data transmission controller generates transmission strobes 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 successively higher numbers of octave strobe states associated with successively higher-level octaves. The transmission strobe states associated with each octave are uniformly distributed during each octave transmission cycle. The data transmission controller generates, during each octaves strobe state, transmission strobe signals identifying an octave associated with said octave strobe state. The interface receives 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.
