Abstract
A combination low-pass filter and a method for reducing bandwidth of an input signal comprises filtering an input signal in parallel with a first type of low-pass filter to produce a first filtered signal having the first type of artifacts, and a second low-pass filter to produce a second filtered signal that does not include the first type of artifacts. Responsive to detecting no significant transition in the input signal, the first filtered signal is output. And responsive to detecting a significant transition in the input signal, portions of the first filtered signal are selectively replaced with portions of the second filtered signal by switching outputs from the first filtered signal to the second filtered signal in transition zones occurring immediately before and immediately after the detected transition in the input signal, wherein the transition zones overlap duration of the first type of artifacts caused by the first filter.
