Class Information
Number: 700/77
Name: Data processing: generic control systems or specific applications > Generic control system, apparatus or process > Multiple modes (e.g., digital/analog) > Fine/coarse
Description: Subject matter where application of a control signal in the "coarse" mode results in a system response of a relatively large magnitude or increments of magnitude and in the "fine" mode results in a system response of a relatively small or more precise magnitude or increments of magnitude.
