Basic formulae are
V (droop) e Iba
(Line time b Sample time)
Capacitor
and V (charge) e IOUT
Sample time
Capacitor
For best results the source impedance should be
kept low using a buffer for example
Because the SH effectively shorts the input sig-
nal during Sample the input should not be sam-
pled during active video Typically the sample is
made during the back porch period of horizontal
blanking For this reason color composite signals
which have color burst on the back porch can
not be passed See EL2090 or EL4093 for this ap-
plication
