  • Receiving circuit for multi-slot receiving provided with circuit for adjusting frequency characteristic of active filter
    Patent number: 7894558
    Abstract: A receiver circuit controls a power source of a front-end circuit and a demodulator using a first power source control signal. Upon receiving data of a plurality of receiving slots having a guard bit provided between receiving slots adjacent to each other, the first power source control signal becomes a power source ON signal before starting receiving of the data, then becomes a power source OFF signal within the guard bit, and becomes a power source OFF signal after completing the receiving of the data. The receiver circuit controls a power source of an active filter circuit using a second power source control signal, which becomes a power source OFF signal after completing the receiving of the data after becoming a power source ON signal before starting the receiving of the data.
