Project 3: Common Emitter Amplifier
Overview

The purpose of this project is to give you some experience in creating a function generator and in computing the gain of a common emitter amplifier circuit.

The top figure shows the user interface for this project. You can get the skeleton of the code.

Get the skeleton of the VS2012 code.

Get the skeleton of the VS2013 code.

  • You need to write your code to simulate the function generator in Calculate.cpp which contain the following codes:

//****************************************************************************
//
// * Generate the input voltage
//   Type: 0 for sine, 1 for square wave (duality cycle 50%) and 
//         2 for triangle wave
//   amplitude is the amplitude of the function
//   phase: control the offset in radian (0 ~ 2 pi)
//   t: the current time
//   delta_t: the time interval between two consecutive samples
//   nSamplesToKeep: how many samples in the array
//   wave: the wave samples
//============================================================================
void Calculate(int type, double amplitude, double frequency, double phase, 
               double t, double delta_t, int nSamplesToKeep, vector<double>& wave)
//============================================================================
{
        // TODO
        I = Vo = Z = 0;
}

  • You also need to write the code to compute the output signal
//****************************************************************************
//
// * Compute the output waveform in the common emitter amplifier setting
//   nSamplesToKeep should be equal to wave.size()
//============================================================================
void Compute(double R1, double R2, double RC, double RE, double beta, 
             int nSamplesToKeep, vector<double>& wave, vector<double>& output)
//============================================================================
{

}

How will we grade it?

You will send a rar files containing only Calculate.cpp and CommonEmitterAmplifier.exe to TA. We will grade your code accordingly and check whether you have copied others' code.
