Hall effect device for use in obtaining square or square root of a voltage amplitude |
摘要 |
In accordance with the Hall effect, a magnetic field applied perpendicular to the direction of current flow through a conductor causes an electric field perpendicular to both the direction of the current flow and the direction of the magnetic field established in the conductor. This effect has been used to produce magnetic field and current detectors, modulators and frequency doublers. In accordance with the present disclosure a portion of the magnetic field is reversed to produce squaring of or obtaining the square root of the amplitude of the voltage used to produce the conductor current.
