ABSTRACT:
A signal varying over a wide dynamic range from a source (10) is input to a summing amplifier (12) along with the output of an adjustable reference generator (14). An error signal output of the summing amplifier (12), a subtraction of the output of the reference generator (14) from the input signal source (10), is applied to a rate network consisting of a capacitor (16) and a resistor (18), with the latter in a feedback loop for an amplifier (20). The output of the reference generator (14) is adjusted to maintain the error signal within the operating limits of the summing amplifier (12) by monitoring the output of the amplifier. During the time interval when the adjustment of the generator (14) is made, a compensating network (24) maintains the output of the amplifier (20) at the level previous to the adjustment interval. This provides a continuous output voltage at a terminal (22) that varies over an expanded range with reference to the input signal.
