One of the basic elements you might use is a Schmitt trigger. In In this installment of Circuit VR, I’m looking inside practical circuits by building Schmitt triggers in the Falstad circuit ...

Figure 1 Use a portion of a programmable-logic device or gate array to implement a Schmitt-trigger buffer (a) by adding either two (b) or four external resistors (c). Thanks to its internal hysteresis ...

the circuit begins to oscillate again and the Schmitt trigger returns the sensor to its previous output. If the sensor has a normally open configuration, its output is an “on” signal when the ...

A single-supply, inverting Schmitt trigger was detailed in a previous Idea For Design (“Comparator Features Symmetrical Thresholds,” by Samuel Kerem, Electronic Design, March 6, p. 124).

(For a sampling of approaches, see references 1 through 10.) The usual hardware approach to eliminating contact bounce comprises an RC filter followed by a Schmitt trigger (Figure 1). You can extend ...
