1. A method of monitoring an operating parameter of a nuclear reactor system at a first location within the reactor containment over a given extended period of time and electrically communicating the information embodied in an analog signal representative of the monitored parameter generated at the first location over the given extended period of time to a remote second location substantially free of the high level of electromagnetic interference encountered in the ambient environment of a nuclear facility, which maximizes noise rejection comprising the steps of: continuously monitoring the operating parameter of the reactor within the reactor containment over the given period of time;  generating the analog electrical output which is representative of the parameter monitored over the given time period at the first location;  electrically, digitally sampling the analog output within the ambient environment of the nuclear facility, at a predetermined number of discrete coordinates along the analog signal respectively on either side of a preselected number of discrete points on the analog signal sufficient to provide a digital representative reproduction of the information being communicated;  electrically transmitting the digital samples of the discrete coordinates from the ambient environment of the nuclear facility to the second remote location;  electrically averaging at the second remote location the predetermined number of coordinates sampled on either side of each discrete point to obtain an electrical representation of the averaged values for the respective discrete points; and  electrically situating at the second location the respective average values in the appropriate locations for the corresponding discrete points in the digital representative reproduction of the analog signal.
