Question: 1 2 . Which op - amps make the input smaller? Background: Some signals contain undesirable components that must be attenuated ( made smaller )

12. Which op-amps make the input smaller?
Background: Some signals contain undesirable components that must be attenuated (made
smaller). The three circuits below contain the same components: a 10 k resistor, an AC voltage
signal source, a capacitor with 2k j of impedance at the signal frequency, and an op-amp.
Their behaviors are not the same.
