Abstract
In order to monitor and display in real time the current frequency of wideband signal source,this paper designs a moni⁃toring and display circuit based on MCU C8051F340、LED and matrix keyboard of 4∗4 matrix keyboard.The MCU receives frequency control words via matrix keyboard,controls signal source to change its output frequency,and then manipulates LED to display current frequency.The design principle of hardware is presented. The results of prototype test prove the effectiveness and reliability of this circuit.关键词
