Abstract
The invention discloses a device for filtering and demodulating multipath signals. The device comprises a capacitor C1, a capacitor C2, a capacitor C3, a capacitor C4, a capacitor C5, a resistor R1, a resistor R2, a resistor R3, a resistor R4, a resistor R5, a resistor R6, a resistor R7, a diode D1, a diode D2, an operation amplifier A1, an operation amplifier A2 and a triode T. The non-inverting input end of the capacitor C1, the capacitor C2 and the operation amplifier A1, the output end of the operation amplifier A1, the non-inverting output end of the diode D1, the diode D2 and the operation amplifier A2, the non-inverting input ends of the operation amplifier A2, the capacitor C4 and the capacitor C3 are sequentially serially connected to form a closed loop. The cathode common terminal of the diode D1 and the diode D2 is connected with the base set of the triode T, the resistor R7 and the capacitor C5. One end of the resistor R1 is connected to the common terminal of the capacitor C1 and the capacitor C2, and the other end thereof is connected with the inverting input end and the output end of the operation amplifier A1. By the arrangement, filtering and demodulating of the multipath signals in transmission can be achieved, and high practicality is achieved.
