Term
Synchronous counter
Definition
Name the broad catergory of counters that all flip-flops are clocked at the same time.
Term
Asynchronous or ripple counters
Definition
Named the board catergory of counters that receives it's trigger from the previous flip-flop's output.
Term
sequential logic
Definition
These types of circuits have the ability to "remember" the order or sequence of an applied input.
Term
Clear/Preset

Because Flip-Flops can be in any state when energized, two inputs are used to enable a predetermined state. Which signal is used to enable a logic level LO on the output of QNOT?
Term
Reset and Set
Definition
The simplest form of a binary storage device is the RS Flip-Flop. What does "RS" stand for?
