Abstract

Professor Takeshi Yanagisawa, who passed away in June 2022, was one of the most outstanding leaders in the field of analog signal processing. Professor Yanagisawa graduated from Tokyo Institute of Technology (TokyoTech) in 1953, and received the M.S. and Ph.D. degrees from TokyoTech in 1955 and 1958, respectively. He has greatly contributed to the development of analog circuits, especially RC active filters. Originally, stable analog filters were realized using inductors, capacitors, and resistors. In order to install filters in a monolithic integrated circuit, the inductors must be avoided because of the difficulty of micro miniaturization. This led to the development of analog filter using resistor, capacaitors, and active elements such as amplifiers.

柳泽武--模拟信号处理的先驱 [CAS 先驱］

柳泽武教授于 2022 年 6 月去世，他是模拟信号处理领域最杰出的领导人之一。柳泽教授 1953 年毕业于东京工业大学（TokyoTech），1955 年和 1958 年分别获得东京工业大学硕士和博士学位。他对模拟电路，特别是 RC 有源滤波器的发展做出了巨大贡献。最初，稳定的模拟滤波器是通过电感器、电容器和电阻器实现的。为了在单片集成电路中安装滤波器，必须避免使用电感器，因为电感器难以实现微型化。因此，人们开发了使用电阻器、电容器和放大器等有源元件的模拟滤波器。
