The circuit consists of unit circuits such as phase discrimination, loss of lock discrimination, square pulse generation, delay and astigmatism alarm. The phase detector is composed of IC1, R4 and C3. When the phase difference between the phase given signal θ and the phase feedback pulse signal θ from the system is Φ=180°, the output point e potential is zero, which is the phase relationship to be maintained after the lock phase control system is locked.
