    摘要: A spectrum-shaped discriminating on/off target indicator which indicates if a signal simultaneously meets prescribed conditions on power level and spectrum shape. Signal power level and spectrum width are simultaneously measured and a DC logic output is obtained only for input signals which have a signal-to-noise ratio equal to, or higher than a preset minimum level though the signal "noise bandwidth" meets the prescribed conditions.
