Abstract :
The noise behavior of an amplifier in compression is studied. For an amplifier input consisting of a CW signal and amplified thermal noise, the signal-to-noise ratios at the input and at the output are determined. The amplitude of the CW signal is shown to influence the noise behavior. This influence will first be shown to exist and will next be quantified by means of a typical hardware setup.
