WEEK 2

Comparison Study of audio amplifier performances using Class AB, B and D topologies in portable audio devices.

In this week, I have to search and take the right circuit diagram for Class D and Class AB amplifier. other than that, I'm doing some discussion with my supervisor about circuit diagram and components that I will use and few things need to be considered before buying all the components.

This is some example of circuit diagram that I had found:

Figure 2: TDA8920BTH 200W Class D Amplifier

Figure 3: UM10155 Discrete Class D High Power Audio Amplifier

Figure 4: Class AB BJT 100W hi-end-audio

Last Thursday, 26 January 2012 at 3pm, there was a meeting with all FYP students at Gemilang Hall. The agenda is FYP updates and System Engineering.
