Voltage - shunt feedback

Current - Series feedback

Negative - Voltage feedback

Positive - current feedback

increase in band width, while the voltage gain becomes less sensitive to variations in components and device characteristics

decrease in overall gain, while the input resistance decreases

increase in distortion, while the output resistance decreases

decrease in input resistance, while the output resistance increases

Coupling Capacitance affects the high frequency $$\left( {hF} \right)$$ response and bypass capacitance affects Low frequency $$\left( {lF} \right)$$ response.

Both coupling and by pass capacitances affects the $$lF$$ response.

Both coupling and by pass capacitances affects the $$hF$$ response.

Coupling Capacitance affects the $$lf$$ response and the bypass capacitance affects the $$hF$$ response.
