A new method for measuring the parasitic amplitude modulation of FM transmitters and oscillators
Abstract
A method for investigating the parasitic amplitude modulation of FM transmitters and oscillators is described which is based on FM compensation of the oscillation and the subsequent measurement of the coefficient of AM oscillation without FM. This method makes it possible to exclude the effect of measuring-channel imperfection and thus to increase the resolving power of the measurement. Experimental results obtained with the method are examined.
