Design of frequency identity testing device
Abstract
Have originally designed of variable frequency sinusoidal wave generator 、 the frequency of measurements, and the interval between cycles of equipment. Utilize mathematical operation of the one-chip computer and control the function, combine the digital circuit of some scale of China, have realized the producing of variable frequency sinusoidal wave and the measurement of frequency , cycle , width of pulse to the signal ,etc. Use one-chip computer make whole system it has to be extremely flexible programmable, can carry on the function to expand and improve the system conveniently .
