Title: Timo Husu: Innovator in Digital Filter Technology
Introduction
Timo Husu is a notable inventor based in Joensuu, Finland. He has made significant contributions to the field of digital signal processing, particularly in the development of transposed digital FIR filters. With a total of four patents to his name, Husu's work has advanced the efficiency and design of digital filtering techniques.
Latest Patents
Husu's latest patents include a method and arrangement in a transposed digital FIR filter for multiplying a binary input signal with tap coefficients. This invention relates to a method for designing such a filter, which comprises a shift register that shifts in the direction of the least significant bit while copying the most significant bit or filling in zero values. The register receives the binary input signal of the filter and has outputs for outputting the content of the desired bit positions. A plurality of bit-serial subtractor and adder elements multiply the binary input signal by N+1 different tap coefficients by combining output bits of the shift register. The subtractor and/or adder elements form a network wherein at least one element participates in the multiplying operation of at least two different tap coefficients. Another patent focuses on the calculation of a scalar product in a direct-type FIR filter.
