I find that the most noticeable impact of a filter's group delay
characteristics is how they pass impulse noise, ie. lightning strike
QRN. The poorer filters tend to turn the short impulse into longer
roaring noise. The difference between filters can easily make the

Doug:
Group delay is a measure of phase shift (and hence time delay) for a
signal as it passes through the filter. Consider a signal swept through
the bandpass of a filter. If the signal always takes the same time to
pass through the filter, regardless of where it is with respect to the
pass

Please reply direct, unless you feel that the group could learn something.
