Abstract
Techniques are provided for the implementation of a signal processing circuit (100) which expands the dynamic range of the signal processing circuit (100) without interrupting the output of the circuit. The techniques can receive an input signal (104), process the signal (104) through one of a plurality of dynamically modifiable signal processing circuits, and switch (130) to processing the signal through another of the plurality of signal processing circuits without disturbing the output of the system.
