Short Content: Abstract: The precise frequency control is the modernization industrial production and the high accuracy test necessary method. May occur based on AD9850 surpasses the 1Hz frequency precision the signal, this regarding the frequency test very important. This article introduced this kind of frequency regulator takes the control core by Atmel Corporation's AVR monolithic integrated circuit Atmega16L, uses 4×4 the keyboard to take the frequency value input device. And AVR monolithic integrated circuit scanning keyboard read-in user hypothesis frequency value. Afterward, the ...
