Question
From the obtained result what is polarity of the output voltage compared to the input?
Transcribed Image Text:4. PROCEDURE
PART 1. DC AMPLIFIER :
1. we Connect the circuit as shown in Figure 3. Wiring sequence :
12V(+)-1, 12V(-)-3, GND-2,15V(-)-6,15V(+)-17,8-42 or (8-44), 48-VM(+),
VM(-)-66 , 7-65.
2. we Switch the power supply on ±12v.
3. we Adjust input voltage as shown in table 1 and observe the output on
voltmeter.(observe the polarities of input and output voltage carefully).
4. we Repeat step 3 with feedback resistance of 4.7k in place of 1k.
