Some articles on voltage, input voltage, input voltage crosses:
... The positive feedback is introduced by adding a part of the output voltage to the input voltage so, these circuits contain an attenuator (the B box in the figure on the right) and a summer (the circle with ... In these configurations, the output voltage increases the effective difference input voltage of the comparator by decreasing the threshold or by increasing the circuit input voltage the threshold and memory properties ... Dynamic threshold (series feedback) when the input voltage crosses the threshold in some direction the very circuit changes its own threshold to the opposite direction ...
Famous quotes containing the words crosses and/or input:
“Life is like walking along a crowded streetthere always seem to be fewer obstacles to getting along on the opposite pavementand yet, if one crosses over, matters are rarely mended.”
—Thomas Henry Huxley (182595)
“Celebrity is a mask that eats into the face. As soon as one is aware of being somebody, to be watched and listened to with extra interest, input ceases, and the performer goes blind and deaf in his overanimation. One can either see or be seen.”
—John Updike (b. 1932)
