Abstract

A system is provided for monitoring a composite signal at the brushes of a generator. The composite signal includes an information signal representative of brush arcing and a recurring noise signal. The system includes a gating network which eliminates the noise signal and passes the information signal therethrough. Timing of the gating network is controlled by a pulse forming network. On the occurrence of a noise signal the pulse forming network produces a disabling signal of predetermined time period exceeding the duration of the noise signal. The gating network blocks all signal passage therethrough for the duration of the disabling signal and thereafter passes signals until the occurrence of the next noise signal. Means is also provided for indicating when the information signal exceeds a predetermined magnitude.
