8 terms starting with Z

Z: Letter symbol used to represent impedance in ohms.
Z0: The characteristic impedance of a device or system.
Zener Diode: A diode that maintains a relatively constant voltage when the reverse voltage across it is increased passed a specific point, called the zener voltage.
zero voltage switch: A circuit designed to switch “on” at the moment the ac supply voltage crosses zero. This technique minimizes the radio frequency interference generated at switch closure.
zero-suppression: The elimination of nonsignificant zeros in a numeral.
ZIF: Zero Insertion Force – A component designed to eliminate the insertion and withdrawal forces during engaging and separating.
Zone cabling: An architectural concept which splits the horizontal cabling into two sections. Eliminates the need to replace the entire horizontal cable in moves, adds and changes.
z-Parameter: The set of parameters for a two port device that relates the input and output voltages to the input and output currents.
