BLOCK DIAGRAM
It can control phase of horizontal wave.
It contains the horizontal saw wave generator and Auto Gain
Control circuit, so that it is able to keep the amplitude constant if
frequency change.
It change the parabola wave inretrace period to constant voltage
in order to reduce load at the amplitude after IC.
