Lab 6: Debouncing Switches with an SR Latch

PDF version

A switch is a mechanical device and as such is much slower than an electronic circuit. When a switch is opened or closed the mechanical contacts do not break or make a connection instantaneously, but can ``bounce'' between open and closed, thus making several transitions. If you were to use a mechanical switch to increment a counter (to count, say, people going through a turnstile), a single closure of the switch could increment the counter many times. In this lab we will use the logic analyzer to look at switch bounce, and use an SR latch to debounce a mechanical switch.
