Abstract
This paper proposes an analog VLSI system structure to estimate real time power spectrum signals. The propose structure is base in a continuous adaptive filter where coefficients are adapted by the least mean square analog LMS algorithm. The system function to be synthesized is represented by the classical fourier series, where the coefficients are adapted independently by analog LMS structure that can be implemented in VLSI technology. Since adaptation is carried out in continuous time, real time computing speed in high frequency spectrum estimation is an important advantage in relation to conventional Discrete Fourier Transform, and even Fast Fourier Transform applications.
