programmed so that the balance is adjusted in E block, and gain is automatically adjusted in Te1.
FOCUS OK CIRCUIT
The Focus OK Circuit compares the DC difference value between the Rfi and Rfo blocks to the standard DC value.
If the Rf level is above standard, Fok outputs L->h to make a Timing Window for turning the Focus On during Focus
Search status.
MIRROR CIRCUIT
The Mirror signal amplifies the RFI signal, than Peak and Bottom Holds it. Peak Hold can follow-up on Defect-type
Traverse, and Bottom Hold can follow-up on Rf Envelope to count the Tracks. The Mirror output is the following: L
