ABSTRACT:
A scalable overflow clamp for controlling the level of allowable digital signal overflow in a gain scaler/summer having an initial full-scale range and a feedback path for establishing a feedback gain. The clamp includes a range scaler for determining the feedback gain and generating a modified full-scale range relative to the feedback gain. The modified full-scale range defines a substantially constant overflow capability relative to the feedback gain. An overflow detector senses the overflow conditions and a selector responsive to the overflow detector utilizes the modified full-scale range when overflow conditions are sensed.
