positive again. In the event of a field
frequency of 60 Hz the signal cannot
be identified as a SECAM signal,
even if the P
H/2 signal is of the wrong polarity, the
identification signal is negative and
the H/2 flip-flop is set to the correct
phase.
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).

PARAMETER
The third demodulator is
demodulating during NTSC
identification or reception only. It is
active during the burst clamping time.
The resulting identification signal
(N
4.43 MHz signal during the NTSC
4.43 part of the scanning and for
NTSC 3.58 MHz signal during the
IDENT
PARAMETER
) is positive for PAL and NTSC
6
NTSC 3.58 part of the scanning. The
reference signal has the (B-Y) phase.
The two identification signals allow an
unequivocal identification of the
received signal. If a signal has been
identified, the scanning is stopped
and after a delay time the colour is
switched on.
