ABSTRACT:
A scanning alarm electronic processor [hereinafter SAEP] for receiving and valuating a predetermined number of analog signals is configured to perform, inter alia, high speed/high resolution analog computations thereon using micro-programmable methods and devices. The SAEP uses unique, parallel pipeline processing of certain functions to obtain the desired high sample rates. The SAEP is divided into two sections which contribute to its high speed performance. Each section contains the circuitry; i.e., modules, necessary to perform the algorithms for half of the predetermined number of analog signals. A common central processing unit module ties the two sections together. The SAEP operates to compute a droop compensated differential voltage for each one of the predetermined number of analog signals, to compute a weighted sum of the differential voltages, and to compare the weighted sum with an absolute value and perform an alarm evaluation.
