Filters Simulators

        This page has simulators for first order low-pass filters.  You have several options.

In all cases you can set the following. Here are links to the various simulators Note: - These simulators are real time.  However, to let you see how the filter(s) behave, we have made the signals very slow - on the order of a few Hertz, or even a fraction of a Hertz.  The time constants should be correspondingly long - on the order of a second (from a fraction of a second to a few seconds).  You won't see much if you stray far from these limits - even though these are long time constants and the bandwidths are quite low.  That's just for purposes of illustration.
