  • Output impedance — The output impedance, source impedance, or internal impedance of an electronic device is the opposition exhibited by its output terminals to an alternating current (AC) of a particular frequency as a result of resistance, inductance and… …   Wikipedia

  • Cable impedance — When radio frequency signals are transmitted via coaxial cable or ribbon cable, the impedance of the cable is significant in determining the load placed on the source and the efficiency of the transmission.Provided the internal impedance of the… …   Wikipedia

  • Negative impedance converter — The negative impedance converter (NIC) is a one port op amp circuit acting as a negative load which injects energy into circuits in contrast to an ordinary load that consumes energy from them. This is achieved by adding or subtracting excessive… …   Wikipedia

  • electrical impedance — Opposition that a circuit presents to electric current. It includes both resistance and reactance. Resistance arises from collisions of the current carrying charged particles with the internal structure of the conductor. Reactance is an… …   Universalium
