Abstract
An adjustable, memoryless, single-valued, monotonic nonlinearity is introduced between the output point of a linear adaptive FIR (finite-impulse response) filter and the output point of the system. A control strategy is derived that permits the simultaneous shaping of both the power spectrum and the amplitude-density function of the system output by jointly adjusting the shape of the nonlinearity and the tap weights of the linear filter. A mechanization diagram and some mechanization considerations are presented
