Because the sensitivity of the phase of a coherence to changes in the phase of a pulse depends on the change of coherence order, P-type signals in homonuclear correlation experiments are insensitive to errors in the phase of the mixing pulse, and hence they show less t(1) noise than N-type signals. This effect is illustrated for the gradient COSY experiment.
