Abstract
An FM audio signal receiver having a characteristic control function includes a receiving circuit for receiving an FM broadcast wave, a received state analyzing circuit for analyzing a state of the FM broadcast signal received by the receiving circuit, an analog-to-digital converter for analog-to-digital converting the FM broadcast signal received by the receiving circuit, a digital signal processor for performing processing for improving characteristics of the digital-to-analog converted signal, a parameter table memory for storing parameters for the digital signal processor and a control circuit for reading out a proper parameter for realizing improvement of a characteristic of the digital-to-analog converted signal from the parameter table memory in response to result of analysis by the received state analyzing circuit and controlling the digital signal processor with the read out parameter. The receiver is capable of improving characteristics of a received signal by processing the received signal with a preset parameter which is read out in accordance with the state of the received signal.
