Abstract

PURPOSE:To form of a three-terminal circuit a reactance filter that has an attenuation pole at neither the origin nor infinity poit, by connecting a tertiary low-pass filter, a tertiary high-pass filter and a seconedry band-pass filter in parallel. CONSTITUTION:The secondary band-pass filter is obtained by connecting one coil and one capacitor each in series as shown by A. Then, the tertiary grid type low- pass filter has an input and an output series arm composed of one coil each and parallel arms between both the arms made of a series circuit of one coil and one capacitor each as shown by B. Further, the tertiary grid type high-pass filter has an input and an output series arms composed of one capacitor each and has parallel arms between both the arms made of a series circuit of one capacitor and one coil each as shown by C. To at least two out of those filters, at least the other one filter is connected mutually in parallel.
