- an introduction or tutorial to the essentials of phase locked loop, PLL frequency synthesizer operation and design. PLL frequency synthesizers are widely used in all forms of radio communications equipment today.
Twisted pair cabling is a type of wiring in which two conductors of a single circuit are twisted together for the purposes of canceling out electromagnetic interference (EMI) from external sources; for instance, electromagnetic radiation from unshielded twisted pair (UTP) cables, and crosstalk between neighboring pairs.
Because of this, one side of the loop feels a force one way and the other side of the loop feels a force the opposite way. This causes the wire loop to rotate. If this rotation is attached to an axle, it can be used to do a lot of useful things. In a car, an electric motor turns the wheel of the car.
