| Abstract: | The concept of phase-locked loop is presented brieny in this paper. A division scheme ofphase-locked multi-frequency is described in de-tail, which can achieve 200 division. First, in the lightof the scheme. the displacement signal is translated into time signal, then, through the phase-lockedmulti- frequency loop, electronic division is achieved. and the direction is detected at same time. Thescheme has the advantages of high division, simple circuit, easy adjustment, and high tlack speed. |
