() The gain versus freguency of a capacitive coupled amplifier is shown below. Draw a graph of gain versus frequency using logarithmic seale for the frequency and linear scale for the gain Gain (dB) Frequency (Hz) Gain (dB) Frequency (Hz) 20 40 80 100 120 34 34 34 32 30 10 30 32 8000 10000 12000 (8) For the circuit shown below, find the nodal voltages, Vi.
