Abstract
A magnetic phase shifter control system comprises a magnetic phase shifter for producing an output signal in accordance with a control command at a predetermined amplification degree, a circuit for suppressing the output signal of the magnetic phase shifter to a level lower than a predetermined level on command, and a circuit for reducing the amplification degree of the magnetic phase shifter when the suppressing circuit is operative, whereby a delay for response due to a dead time which the magnetic phase shifter inherently has is eliminated.
