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

Circuit and method for dynamically modifiable signal processor

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

Active filter circuit with dynamically modifiable internal gain

A signal processing system () comprises an input terminal (), and a main path having a main filter input gain unit () coupled to said input terminal (), a main filter () and an output gain unit (). An auxiliary path includes an auxiliary filter input gain unit () coupled to the input terminal (), an auxiliary filter () and an auxiliary filter output gain unit (). An adder () is coupled to the output gain units () for generating an output signal to an output terminal (). The gains of the gain units are adjusted by a control unit () responsive to a detecting signal from a detector ().
