Title:
ASK復調器、無線通信装置、並びに反射波通信システム
Document Type and Number:
Japanese Patent JP4631571
Kind Code:
B2
Abstract:
To perform space-saving mounting at low costs and low power consumption.
An ASK demodulator is composed by using an analog switch, a DC blocking capacitor, an inverting amplification circuit, and an inverter instead of a comparator and an analog amplifier. An ASK signal can be input to a digital circuit without determining a threshold, and the number of components and a mounting area can be reduced. A module in an IC circuit is utilized for mounting, integration with a digital processing circuit can be made, and the space can be saved at low costs.
