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.

In this type of semiconductor electrons flow. Antimony —> Sb — Easier than heating.

Current goes in the material.

In this type of semiconductor a positive charge appear to flow.

A solid-state component that combines an n-type and a p-type semiconductor. Electrons flow from the n-type to the p-type.
