coupling is a computer program, which is meant for the maintenance of the cohesion , coupling is inversely proportional to cohesion. When coupling and cohesion is combined then it acts as support to the high readability and maintainability of a computer program.
resilient plate is used to protect fluid coupling from damages and takes the overload acting on the device ,
control coupling content coupling common coupling data coupling external coupling message coupling
There are many like flexible coupling, jaw coupling, sleeve coupling, tire coupling, pin and bush coupling, rigid coupling, etc
transformer coupling
Control coupling:Control coupling is one module controlling the flow of another, by passing it information on what to do (e.g., passing a what-to-do flag) Data coupling:Data coupling is when modules share data through, for example, parameters. Each datum is an elementary piece, and these are the only data shared (e.g., passing an integer to a function that computes a square root)
rc coupling is a coupling that involves capacitor aand resistor
no.transformer coupling gives higher gain
Direct coupling
We don't know much about the circuit these capacitors are in, but they are coupling capacitors. Coupling capacitors isolate DC between stages or circuits, and they couple AC between those circuits or stages. Only the signal gets in and goes out. The DC the stage operates on is isolated from stage to stage.
Loading of Rc coupled amplifier occurs, if you doesnt use coupling capacitors...... If avoiding input coupling capacitor the amplifier will load the function generator.. For more details go to http://mycircuits9.blogspot.com
