Abstract
PURPOSE:To reduce the interference between filters, by connecting two diodes, at least, in parallel to another filter circuit in respect to a circuit which switches band- pass filters by diodes. CONSTITUTION:In case that an input passes through a band-pass filter 3 or 4, diodes 7, 11, and 16 or diodes 8, 12, and 16 are conductive, and all other diodes are nonconductive. At this time, a diode 15 in the input side is made nonconductive to reduce the influence of filters 5 and 6 upon filters 3 and 4. In case that the input passes through the band-pass filter 5 or 6, diodes 9, 13, and 15 or diodes 10, 14, and 15 are conductive, and all other diodes are nonconductive. The diode 16 is made nonconductive to reduce the influence of filters 3 and 4.
