Abstract
A circuit for detecting nuclear resonance absorption is described that, unlike the rf bridge, is simple to construct and adjust and very insensitive to microphonics. The voltages in two branches of an rf network, one of which contains the coil and sample, are rectified by diode detectors and the audio outputs combined in such a way that noise modulation from the rf generator is balanced out but the desired signal is not. Experimental performance is discussed and typical signal-to-noise ratios are given.Keywords
