Automated Signal-to-Noise Ratio MeasurementComputer-controlled spectrum analysis gives rapid results for communication systems. Locates carrier signal in intermediate-frequency band and measures both carrier amplitude and amplitude of noise in several channels near carrier frequency. Computer then computes ratio of signal to average noise. Because measurements and calculations are rapid, system used in fading communication channels.
