Consider the following statement: In feedback amplifiers, concerning the connections between the direct amplifiers and the feedbacks network, a shunt connectiın at the input part servers to set an increased versiın of the input impedance of the direct amplifier, whereas again a shunt connection at the output part services to set a decreased version of the output imdepance of direct amplifier. Explain what is wrong with the statement above by drawing representative circuit diagrams and outlining the necessary calculations.

Explain what is wrong with the statement above by drawing representative circuit diagrams and outlining the necessary calculations.
Given that,
Input connection is shunt type as well as output connection is also shunt type.
So it is a trans-resistance type amplifier.(Voltage shunt feedback)
Feedback type: current controlled voltage source(CCVS): In this type of connection, output voltage is controlled by input current:
(Source signal: current, output signal: voltage)
