Pin 5 is the output pin. The output from Pin 5 is input to the
SIF via a 6 MHz bandpass filter (BPF).
When 5.5 MHz is input to Pin 1, the spectrum shown in
Figure 10 is obtained at Pin 5. Even if there is a 5.85 MHz
NICAM signal, the D/U (desirable/undesirable) ratio at Pin 5
increases and the buzz characteristic does not deteriorate.
When 6 MHz is input at Pin 1 and there is a 6.552 MHz
NICAM signal, then 6.552 MHz is mixed with 500 kHz to
make 6.052 MHz. This becomes an interference signal and is
within the band for 6 MHz. Therefore,for 6 MHz input, Pin 4
is grounded with 10 k
to stop the oscillation and pass
through the input signal 6 MHz as is.
