ABSTRACT:
A signal processing circuit with enhanced response time includes a data limiter circuit having an input and an input capacitor having one terminal coupled to the input. A first selectively actuable voltage clamping circuit responds to a first comparing circuit and is coupled to the input for preventing the voltage at the input from exceeding a predetermined upper voltage. A second selectively actuable voltage clamping circuit is responsive to a second comparing circuit and is coupled to the input for preventing the voltage at the input from decreasing below a predetermined lower voltage.
