Method and device for comparing the phases of two binary signals D, K with different frequencies, where a signal K has a fixed known frequency. A flank of the signal D and the two flanks of the signal K are fed to their respective flip-flops A, B and C, the output signal of which affects an element G. The element G can adopt the two active states ôlow levelö and ôhigh levelö in addition to a non-active state. The output signals of the element G are used as the phase comparison signal. <IMAGE> |
