Output signal of Hall-effect squaring multiplier HG is fed to differential amplifier A. Amplified difference controls current through lamp that determines resistance of photoresistor r which, with 2N174, controls Hall current derived from voltage source.-H. H. Wieder, Square-Root Computer Uses Hall Multiplier, Electronics, 37:4, p 30-31.
