Abstract :
Sensitivity in digital microwave signal analysis strongly depends on the signal/noise ratio. The letter describes a method which improves the signal/noise ratio and therefore the sensitivity of monofrequent amplitude and phase measurements by means of sampling below the Nyquist frequency.
