Abstract：
The embodiment of the invention provides a universal frequency modulator and a frequency modulation method and device. The general frequency modulator comprises a configurable all-digital phase-locked loop, and the all-digital phase-locked loop comprises two loops, namely a loop A and a loop B; the loop A comprises a binary phase discriminator, a digital loop filter, a numerical control oscillator, a dual-mode frequency divider, a differential integral modulator, a digital time converter and an integer frequency divider; the loop B comprises other parts, except the numerical control oscillator, in the loop A; the output end of the digital loop filter in the loop A is connected with the input end of the numerical control oscillator; output signals of the numerical control oscillator are respectively input into the dual-mode frequency dividers in the loop A and the loop B; and the output end of the digital loop filter in the loop B is connected with the input end of the differential integral modulator in the loop A.
