Girator

The use of girator is to replace induktor that is too large, heavy and expensive. For example, the filter can pass the path was built using the condenser, resistor, and brace, without induktor.

Girator circuits are often used on the Tools phone or device that is connected to the POTS system. Allows phone to be smaller. Girator also be used for graphic Equalizer hi-fi, parametrik Equalizer, pass-line filter, the filter stop-line, swishing filter, and filter signals parlormaid FM

There are a few of which use girator as induktor not possible.

High voltage, where voltage far exceeds the working voltage brace.
Frequency radio system, where the radio frequency induktor for relatively small and easily made.
Power modifier, where the coil is used as a temporary power storage
