The application of narrow-band sampling theory and a system engineering approach to the design of a powerful but economical data acquisition and processing system is described. A commercially available recorder and filter bank are combined in an acquisition system which produces digital tape for later analysis. The program libraries normally associated with general-purpose computers provide the core of a system of processing programs compatible with the recorded tape. Important system parameters are given and illustrations of the use of the system are provided.
