Abstract :
After discussing the need for a radio frequency bridge of general utility, the bridge method is critically compared with indicating, null, and potentiometer methods. Certain precautions in the shielding and coil construction of such bridges are considered; and the specific form of bridge used by the author is described in detail. Beat note with amplification and telephone indicator of balance point are used. Some applications of the bridge are then given.
