Using LTSpice, simulate the circuit below, use 2N3904 for the transistor.
Part ! DC simulation: Measure VCE and Ic. Use .op for the simulation cmd. Remove all capacitors and input signals first.
Part 2 AC simulation: Connect all capacitors now and apply an AC signal at the input with an amplitufe of 1mV and a frequency of 1kHz. Determine the Voltage gain of the circuit by dividing Vo with Vin.
Show the output for both the DC and AC analysis.
Take a screenshot of the circuit and the output voltages and waveforms. Paste in a word file, write your answers, then save as pdf.
