Flip-flops are extremely simple electronic circuits, forming the basis of clock circuits, memory circuits, buffers, and shift registers. Through his dilly-dallying with digital logic, [Jeffrey ...

The logic is actually done by crystal rectifiers, but the tubes do inversion. To make an and/or/invert gate requires a single triode or half of a 6J6A. A D flip flop requires three tubes or two ...

The first flip-flops, known as "trigger circuits," were constructed with two transistors. Subsequent designs use two NOR or NAND logic gates. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other ...
