ABSTRACT:
In nuclear magnetic resonance apparatus employing detection channels in phase quadrature an excitation-pulse transmitter includes an arrangement of switches and associated delay lines to enable successive pulses to be produced in phase quadrature and alternate pulses to be produced in phase opposition. The receiver output signals corresponding to the quadrature pulse-pairs may then be processed to cancel the effects of phase error and unequal gain in the detection channels and the signals corresponding to the opposing pulse-pairs may be processed to cancel systematic noise.
