FM radio circuit for MTS
Product specification
TDA7021T
Fig.9 Test set-up; V

= 30 mV; f
i
= 76 kHz; selective voltmeter at output has R

Ω
and C
i
≤
8 pF; f
o
= f
i
.
Note to Fig. 9
This test set-up is to incorporate the circuit of Fig.5 for mono operation or the circuit of Fig.8 for stereo operation.
For either circuit, replace the 100 nF capacitor at pin 6 with R6 (100 k
Ω
) as shown above.
