First Order (Single Pole) Filter Simulators

Filters Simulators

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

You can see either the output alone, or the output and the input.
You can have a one-shot simulation - where there is only one display which does not repeat.

In all cases you can set the following.

Input amplitude
Input frequency
Filter time constant

Here are links to the various simulators

See the output - one shot/single trace.
See the output - repeating display.
See the output and input together.

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.
