Flip Flop Circuit Design

circuit design
The process of circuit design can cover systems ranging from complex electronic systems all the way down to the individual transistors within an integrated circuit.
n - techniques used to connect active (transistors) and passive (resistors, capacitors, and inductors) elements in a man­ner to perform a function (that is, logic, analog). [1994 National Technology Roadmap for Semiconductors]
Before an electrician selects the correct cable and MCB for a circuit, the circuit is designed to ensure it's safe operation. Consideration is made for the type of circuit, the load on the circuit, whether the cable passes through building insulation and other additional factors.

reversal: a decision to reverse an earlier decision
A light sandal, typically of plastic or rubber, with a thong between the big and second toe
A backward handspring
interchange: reverse (a direction, attitude, or course of action)
