PROBLEM TO BE SOLVED: To store and retain a maximum value of the strength of a reception signal in a series of received signals, and to provide a reception signal strength display circuit of a radio communication machine that is constituted to perform display according to the needs of a user. SOLUTION: An A/D conversion circuit 4 a reception signal strength signal being detected by an AGC circuit 13 that is equipment at a reception part 11 of a radio communication machine 1 is converted to a digital signal. A peak/hold circuit 5 detects the peak value of the converted digital signal and retains it. A display 6 displays the peak value of the reception signal strength being converted to a digital signal that is retained by the peak/hold circuit 5. The display time of the maximum value in the display 6 is controlled to proper time by a control circuit 7. |
