ABSTRACT:
In an NMR probe containing an observe coil and a decoupling coil, the signal-to-noise ratio of the observe channel is improved by inserting a back-to-back parallel combination of diodes in series with the decoupling coil to present an infinite impedance in the decoupling channel in its passive state for induced RF signals from the observe coil.
