Audio Amplifier Power Output selection: 3.2 W, 5.6 W, 7.1 W, 8.4 W, 11.5 W, and 16.3 W
Audio Amplifier Input Voltage (peak) selection: 150mVpeak, 200mVpeak, 250mVpeak
Audio Frequency: 20 Hz – 20 KHz
Design, simulate, and test an Audio Amplifier which delivers one of the above power outputs to an 8Ω speaker load. The output power of your design and the input signal of your design must be selected from the above list. The audio frequency range is between 20 Hz to 20 KHz, so the operating frequency of your design will be within this range. The measuring equipment should display the output power and the input signal of your design. You are required to use either or both NPN and PNP transistors, but not an op-amp. It is recommended that you use multistage amplification of any class amplifiers of your choice. You should try to minimize your usage of components and be cost effective.
