Abstract
In this brief, it is shown that the power of the intermodulation noise of a wide-band amplifier with a Gaussian input signal, can be estimat ed by the total harmonic distortion (THD) with a sinusoid input signal of appropriate amplitude. The THD is, as opposed to the intermodulati on noise, easy to measure and use as a design parameter. A novel metho d based on probability density functions is used. The method is demons trated by a practical example, and a mathematical experiment is made t o validate it.
