"4. Show the connection of an LM124 quad op-amp as a three-stage amplifier with gains of +15,
-22, and – 30. Use a 420-kn feedback resistor for all stages. What output voltage results for
an input of V, = 80 µV?
5. Show the connection of two op-amp stages using an LM358 IC to provide outputs that are 15
and – 30 times larger than the input. Use a feedback resistor, Rp = 150 kN, in all stages.
