Latest Patents

One of his latest patents is for a computer-controlled transversal equalizer. This invention features an adjustable equalizer network that includes a series chain of N all-pass amplifier stages driving N+1 scaling circuits. These circuits are connected to a final summing circuit that adjusts the frequency response at M+1 frequency control points. The goal is to achieve a predetermined ripple-free minimum phase shift frequency response over a specified frequency range. The scaling circuits utilize coefficients determined by Fourier analysis, ensuring that the filter encompasses M+1 contiguous bands within the frequency range. The calculation of these coefficients and the control of the scaling circuits are accomplished through digital computation and manipulation. Some embodiments may incorporate passive circuits or linear analogue circuits, which can be controlled manually or by a computing device.
