Title:
METHOD AND DEVICE FOR CALIBRATING SIGNAL AMPLITUDE, AND COMPUTER STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/094893
Kind Code:
A1
Abstract:
A method and a device for calibrating signal amplitude, and a computer storage medium, the method comprising: generating a sinusoidal signal using a crystal oscillator (101); detecting amplitude value of the sinusoidal signal, and converting the amplitude value into a corresponding level signal (102); comparing the level signal with each of a first reference signal and a second reference signal, to obtain a first amplitude status signal and a second amplitude status signal (103); generating a current control signal according to the first amplitude status signal and the second amplitude status signal (104); and inputting the current control signal to the crystal oscillator, so as to adjust the amplitude value of the sinusoidal signal generated by the crystal oscillator (105).
