Abstract
A system includes an input for receiving an input signal, a filter having a changeable time constant, and a control circuit for changing the filter time constant in response to a property of the input signal.
Claims18
An apparatus comprising:
- an input for receiving an input signal;
- a filter having a changeable time constant;
- and
- a control circuit for changing the time constant in response to a property of the input signal.
1 more element
An apparatus comprising:
- a filter for receiving an input signal and having a changeable time constant;
- and
- a control circuit for increasing the time constant during a time period following initial receipt of the input signal.
An apparatus comprising:
- a multiplexer having a plurality of inputs for receiving a plurality of input signals;
- a filter for receiving one of the input signals from the multiplexer and having a changeable time constant;
- and
- a control circuit for changing the time constant in response to changes in the input signals.
1 more element
A method of reducing settling time of an electronic system, the method comprising the steps of:
- providing a filter having a changeable time constant;
- connecting an input signal to the electronic system;
- using the filter to filter the input signal to produce a filtered signal;
- and
- changing the time constant in response to a property of the input signal to reduce a settling time of the filtered signal.

A method of reducing settling time of an electronic system, the method comprising the steps of:
- providing a filter having a changeable time constant;
- alternatively connecting one of a plurality of input signals;
- using the filter to filter the input signal to produce a filtered signal;
- and
- changing the time constant in response to a change in the input signal to reduce a settling time of the filtered signal.
