ABSTRACT:
Apparatus and method for extending the effective dynamic range of pulse measure and pulse display devices by providing dynamic gain switching, with an associated gain or attenuation coefficient that assumes one of a plurality of two or more values, depending on the instantaneous magnitude of the signal received or upon the choice of an external controller. The amplification path may be one of a plurality of mutually exclusive parallel paths. Alternatively, the amplification path may be a serial combination of an arbitrary subset of a collection of amplification paths. The choice of amplification path may be made automatically by a fast-acting sensor such as a signal comparator or may be made by an external control provided by a human operator or computer and may be overridden by an externally produced control override signal.
