MPX Block
1. HCC (high-cut control frequency characteristics (pin 1)
During HCC control, the output signal frequency characteristics are determined by the capacitance of the external
capacitor connected to pin 1.
2. Pilot cancellation adjustment (pins 2 and 3)
The pin 3 pilot cancellation waveform is a 19 kHz signal that does not include a third upper harmonic component, as
shown in the figure above. Also, no capacitor is required between pin 3 and ground since this signal is in phase with
the pilot signal. Good pilot cancellation characteristics can be acquired in the left and right channels by adjusting the
variable resistor, since the signal does not include a third upper harmonic component.
3. Separation adjustment (pin 9)
The separation is adjusted by varying the sub-decoder input level with the pin 9 variable resistor. Only the sub-decoder
level changes when the variable resistor is changed; the mono (main) output level does not change. Also, the decoder
high-band separation in the sub signal frequency band (23 to 53 kHz) will not degraded if the external capacitor C’s
value is made sufficiently smaller than the variable resistor’s impedance.
