ABSTRACT:
A multi-channel electrical signal ratioing circuit for a source delivering an electric analog pulse signal sequence having a broadened choice of ratio denominator terms provided by parallel-connected DC-coupled individual signal ratioing circuits each incorporating its own associated gated integrator, variable gain amplifier and at least one sampling circuit to form the several ratios needed. The basic ratioing circuit includes means for compensating against the effects of background influences, such as amplifier signal offsets, line voltage variations and changes in electrical system gains or other anomalies affecting ratio determination accuracy.
