The five basic types of couplings are capacitive, inductive, radio frequency, common impedance, and conducted. Of these five the ones that affect the project are capacitive, inductive, and conducted. Capacitive noise is coupled into a circuit by a capacitive effect. This occurs when a voltage difference between two conductors is separated by air or other insulating materials. This sepperation creates a capacitor through which noise can be coupled.
Inductive noise is coupled into a circuit by an inductive effect and is current based.
Current flowing through one circuit induces noise current in another circuit. Conducted noise is coupled into a circuit by the transmission of noise by wires or other conducting materials. We found that when the circuit was connected it gave us these results. I found that this circuit is works well between the frequency of 10 Hertz and 10,000 Hertz. This is shown in the following table and graph.
