1. A backward somersault.
2. An electronic circuit that can assume either of two stable states.
In computing, another name for a bistable circuit.
A circuit that alternates between two possible states when a pulse is received at the input. For example, if the output of a flip-flop is high and a pulse is received at the input, the output “flips” to low; a second input pulse “flops” the output back to high, and so on. Also called: bistable multivibrator.
