Title: Seppo Ingalsuo: Innovator in Digital Filter Technology
Introduction
Seppo Ingalsuo is a notable inventor based in Tampere, Finland. He has made significant contributions to the field of digital signal processing, particularly in the design and implementation of digital filters. With a total of three patents to his name, Ingalsuo's work has advanced the capabilities of digital filtering technologies.
Latest Patents
Ingalsuo'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 a transposed digital 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. Additionally, he has developed a method for calculating a scalar product in a direct-type FIR filter.
