prototype electron microscope in 1931, capable of four-hundred-power magnification; the apparatus was the first demonstration of the principles of electron microscopy. Two years later, in 1933, Ruska built an electron microscope that exceeded the resolution attainable with an optical (light) microscope.

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.
