Ripple counter

Grimley (G10), 1945 Film flow in tubes and channels (water, water + surfactant), co- and counter-flow of air. Wave observations, onset of rippling, surface velocity, velocity distribution, film thicknesses, effects of surface tension and surfactants. 

The question arises, why one would use the more complex synchronous counters rather than the simple asynchronous counters One important reason is that in asynchronous counters the various count sequences must ripple from one flip-flop to the next. This means that an incoming count on the first flip-flop, which will...
