Title:
信号補償回路及び復調回路
Document Type and Number:
Japanese Patent JP4321959
Kind Code:
B2
Abstract:
The demodulator according to the invention comprises a negative feedback loop which slowly compensates for a DC potential of a demodulated signal through an integrator formed of a resistor and a capacitor, and a negative feedback loop which senses a amplitude of a demodulated signal and rapidly charges or discharge the capacitor in response to the result of the sensing, wherein the two negative feedback loop operate independently of each other.
