Abstract
A technique for resetting a HPF for improving its settling time in response to a sharp transition in its input signal, by rapid input and clocking through the high-pass filter (HPF) of new data samples after occurrence of the sharp transition. The new data samples comprise an artificial ramp representative of the expected average slope of the input signal that should be maintained after occurrence of the sharp transition. The artificial ramp can be generated using “a priori” knowledge of the expected average slope of the input signal, or alternatively, can be generated using a direct measurement of the slope of the input signal at the time the HPF is to be reset. In the event that both the direct slope measurement and “a prior” slope knowledge are available at the time the HPF is to be reset, and they differ from each other, it is desirable to generate an artificial ramp whose slope provides a smoothed transition from the latter slope measurement to the former slope.
