A Guide to Debouncing
my.eng.utah.eduwandered in the hundreds of millivolts range for up to 8 msec. Then it suddenly snapped to a one. As the signal meandered up to near a volt the scope interpreted it as a one, but the analog’s continued uneasy rambles took it in and out of “one” territory. The MSO showered the screen with hash as it tried to interpret the data.

1 Bayes’ theorem

Bayes’s theorem for probability densities is formally similar to the theorem for proba-bilities: f(x|y) = f(x,y ...
