What is that?

Is a machine that reads and send signals.

Is a continuous signal in which one time-varying quantity (such as voltage, pressure, etc.) represents another time-based variable.

may be analog or digital signals. Digital signals, which are the main type of signals used today, consist of rapid pulses of voltage that repeatedly switch the current off and on.

a solid substance that has a conductivity between that of an insulator and that of most metals, either due to the addition of an impurity or because of temperature effects.
