PURPOSE:To perform band division without a mass capacitance, by converting channel-divided signals directly after causing them to pass through prescribed filters. CONSTITUTION:Input signal Ei is subjected to time division through multiplexer 10, and respective signals are inputted to transversal low-pass filters 201-204. Signals x1-x4 are given to the inversion input of amplifier 161 through resistances R10-R40. This inversion input is connected to the output of amplifier 161 through resistance 18. The noninversion input of amplifier 161 is grounded, and the output becomes signal y1 through inverter 221. Signals x1 and x2 are given to the inversion input of amplifier 162 through resistances R12 and R22. Signals x3 and x4 are given to the noninversion input of amplifier 162 through resistances R32 and R42. Signals are connected similarly. |
