week 5

How high of signal source impedance exist and still provide an output signal from an inverting amplifier circuit? Explain your thoughts.

What effect would the signal source impedance have on the non-inverting amplifier?

week 6

Share an application where a math operation is needed and which operational amplifier circuit will perform the task.

The general purpose of operational amplifier was used as a comparator. Comment on the distinction between the usage of the op amp as a difference amplifier and the comparator.
