Note
7. AUDIO signal quality is measured with feedback components as shown in figure 18 and with 500 mV peak to peak input to AFCIN.
Discriminator gain is set with D = 3 and M = 40 and V
= 3·75 V and a crystal at 14·85 MHz. SINAD is defined as the ratio of wanted signal
to all unwanted output, measured simultaneously with filters. The hum and noise figure is defined as the ratio of output power at AUDIO when
AFCIN is unmodulated to the output power when AFCIN is driven as specified above.
