(Note 11) Output impedance of SECAM DET (R28)
(Note 12) The sync signal at T29 must lag behind the SECAM color bar signal synchronization by 1.5µs (Fig. 1).
(Note 13) The sync signal at T29 must lag behind the PAL color bar signal synchronization by 1.5µs (Fig. 6).

and take “H”, and calculate R28.
Assign to V28 as when generating 100µA from pin 28 by adding 5V to pin 27
VSAPD1 : Assign to VPD1 the DC voltage at T25 when a sine wave of 1.0625MHz is input to T14 and VPD2 the DC
VSAPD2 : Assign to VPD3 and VPD4 the voltage at T25 and T26, respectively, when a sine wave of 627kHz is input
VSCMP1 : Apply the above-mentioned VPD1 and VPD2 to T25 and T26, respectively and measure the voltage at T28.
VSCMP2 : Apply the above-mentioned VPD3 and VPD4 to T25 and T26, respectively and measure the voltage at T28.
