Abstract
A system having a pair of input signals, one of which is modulated and transformed into a pair of signals phased 180.degree. apart. These signals are acted on by a FET correlator where the second input signal controls the FET gate. Correlator output is amplified and a blocking capacitor removes DC offset, a synchronous switch operated at the modulated frequency converts the remaining AC to DC which is amplified to the output.
