In the lecture, the different amplifier types were presented as black boxes. Thereby the adjacent picture was used for the input and output quantities and the ideal resistance values were derived. In the following, you are to consider how these can be converted into each other by interconnecting them with other passive, electrical components.
How can the following amplifiers be converted into each other? For each, draw a circuit with the amplifier as shown opposite as a black box.
The TINA simulation is generally used to simulate circuit diagrams. In the following, a block diagram of the feedback (see picture) is to be examined. Please download the following file and work on the task contained in it.

Compare the results with the findings from the chapter feedback!
For the principle of negative feedback, the adjacent block diagram was given in the script. Here $A_\rm D$ is the so-called differential gain, i.e. the gain of the difference between the input voltage $U_\rm I$ and the feedback voltage.
