Disconnect the RC series-parallel network to measure amplifier’s quiescent point and its voltage gain. Disconnect the RC series-parallel network and the amplifier. Apply the sinusoidal signal of the function signal generator into the RC series-parallel network. Keep the signal amplitude still (about 3V). The frequency changes from low to high, so the output amplitude of RC series-parallel network would change. When the signal source reaches a certain frequency, the output of RC series-parallel network will reach the maximum value (about 1V). And when the input and output are with the phase, the signal source frequency is .
