ABSTRACT:
The respective ends of input wiring on a printed wiring board of a signal transmission circuit are connected to an input terminal section and a transistor. One terminal of a first capacitor and a first resistor are respectively connected to the input wiring. A leading-side transmission path from a connection point with the first capacitor to a connection point with the input terminal section is formed by only a conductive pattern. An intermediate transmission path from the connection point with the first capacitor to a connection point with the first resistor includes two or more through holes or via holes. The intermediate transmission path is placed near grounding wiring on the printed wiring board. When one terminal of a second capacitor is connected to the intermediate transmission path, a transmission path between the respective connection points with the two capacitors includes one or more through holes or via holes.
