An Autoranging Scale Expander

Abstract
A scale expander for analog signals is described in which the output is presented in the form of an integer voltage (the suppressed voltage) and a voltage representing the remainder of the input signal. Choice of the range (magnitude of suppression) is rapid and automatic. The instrument can be used, as an interface module, with a very wide variety of analog data systems. A few illustrative applications are given. Advantages in instrument performance over presently available circuits are documented.
