Abstract

The use of multiplier circuitry is shown to provide a simple way of simultaneously measuring the in-phase and quadrature (phase-angle) components of the signal in alternating current polarography. When used with previously developed circuitry an extremely versatile instrumental approach is available for detecting the second harmonic and intermodular (frequency difference) components in addition to the in-phase and quadrature components of the fundamental harmanic.
