PURPOSE:To correct frequency characteristics not sacrificing the portability nor depending on the transmission side. CONSTITUTION:The channel designated by the channel designation data 8 outputted from a channel designation part 9 of reception signals 1 is received by a reception part 2 and electric field intensity is detected by an electric field detection part 4. Channel information 10 showing which channel is received is supplied from the channel designation part 9 to a correction circuit 6. Based on the channel information 10, the detection value 5 outputted from an electric field part 4 is corrected. By this constitution, the signal from a transmission side is unnecessitated, the receiver of a wide band is unnecessitated, the shape of this device can be reduced and it is made to be suitable to portability. |
