NA in several peak to peak amplitude of and vary the frequency from SUZ steps. Display both the input (source) and output (load) signals on the oscilloscope. Try to measure the amplitude of the output signal, and the amplifier gain as unit-less value, and in dB as well. Tabulate your results as illustrated in Table-2.

Calculations and Discussion: 1- Draw the frequency response of the amplifier on a semi-log paper. 2- From the frequency response plot, determine the —3 dB cut-off frequencies fand fu of the amplifier, and find the bandwidth. 3- Calculate the lower break frequencies fuc, fls, and fle due to the coupling and bypass capacitors. Find the dominant corner frequency and compare it with the measured value off 4- From your plot, determine the unity-gain frequency fr. 5- Calculate the theoretical value of the mid-band gain, and compare it with the practically measured value. 6- What is meant by one decade, and one octave?
