Decrease the frequency of the inpu t signal to less than 100 Hz and note how the output changes. Increase the frequency of the input to more than 1 MHz and note how the output changes. Increase the amplitude of the input signal to more than 300 mV peak- to-peak and note how the output change. Comment on the results. Q5. Indicate the values of f1, f2 and the bandwidth of the amplifier.
