Spectrum Signature Predictions+

This paper develops expressions for the spectral power density of a simple triode amplifier. The technique employed is straight-forward and employs a nonlinear triode model based on a piecewise linear approximation to the static characteristics of the device. The technique is not restricted to triodes and may, employing the proper device model, be used to solve other types of amplifiers. The solution is given as an iterative process of successive approximations.
