Biphase amplifier for precision controlled rectification and polar logic operations

A biphase amplifier is a positive-negative controlled unity gain amplifier. Its circuit is simple but very useful in the fields of control, instrumentation, and communications. The use of a biphase amplifier for some novel applications, e.g. polar logic operations and precision controlled rectifications, is described. The circuits described were experimentally tested and found to be quite satisfactory.<
