<p>PURPOSE:To prevent the disturbance in period of the pulse signal when the phase deviation between a phiA signal and a phiB signal becomes apparent. CONSTITUTION:The periods of a phiA signal and or a phiB signal are counted up at (n) bits. The down-counter borrow signal, which rises up 2 times in one period of the phiA signal or the phiB signal, is generated by counting down the upper (n-3) bits in the counted-up period. The pulse signal is generated by dividing the down-counter-borrow signal by 2<2>=4. The period of the obtained pulse signal is constant, that is, T1+T2=T3....</p> |
