Second part is the oscillator itself. Hardware circuit that converts a DC signal to an AC signal. Frequency of the oscillator is determined by a RC combination, looking for a range of 1.5 to 12.5 kHz. Output voltage should be 1 VRMS. Need to make an oscillator with almost no harmonic distortion.
Third subpart is the amplifier. Will take the output signal of the Oscillator portion and amplify the wave form. Output voltage determined by a resistor, looking for 1 to 6 VRMS.
