Subject: [SI-LIST] Re: sin(x)/x interpolation
sin(x)/x in the time domain is the rough approximation (or consequence) =
of a
brick-wall filter in the frequency domain ... flat response below some
frequency, negligible response above it.
On oscilloscopes when you are displaying a sweep rate that is fast =
relative
to the sample rate, sin(x)/x gives a 'smoother' picture than linear
interpolation between samples, which can be either a good thing, or
deceptive.
