    摘要： A method and apparatus for producing a vertical center line and horizontal synchronization signals for a television display device having a horizontal oscillator with a square wave output. The square wave signal is fed to two differentiation circuits. Each differentiation circuit differentiates the square wave and feeds the differentiated signal to a corresponding gate circuit, wherein each gate circuit is able to switch between an on and off state in response to the differentiated signal. A signal combination circuit combines the output signal of each gate circuit so as to provide a composite of the horizontal synchronization and vertical center line pulses to the television display device. The center line pulses are temporally centered between the horizontal synchronizing pulses because of the rising and falling edges of the square wave signal used as the triggering event for the gate circuits.
