AC CHARACTERISTICS
Measured in the test circuit of Fig.5; V

= 25
°
C.
AC conditions: (1) input signal (V
i
) of 815 mV p-p for L = 1, R = 1 (mono) f
m
= 1 kHz (= 80% modulation). (2) MUX input
signal (V
i
) of 1.2 V p-p for L = 1, R = 0 and no DBX; f
m
= 1 kHz (stereo) and V
pilot
= 200 mV p-p. (3) S1 open, unless
specified (without L
R filter); voltage controlled oscillator (VCO) adjusted to 188.8 kHz at V
i
= 0 V; values are measured
with an external IF roll-off network (
2 dB at 31.5 kHz = 2f
H
) at the input (dashed components RS and CS in Fig.5).
All the above conditions apply unless otherwise specified.
