Dynamics processing is performed by amplifying devices where the gain is automatically controlled by the level of the input signal. Non-linear components simulating tube amplifiers can be used in these devices to make musical signal audibly dense. This paper deals with the simulation of tube amplifiers using the power polynomial approximation of transfer characteristic and with the computation method of power polynomial coefficients according to the required higher harmonics ratio.
