Hanz Matthew Mangaliman Salenga, is this an assignment as part of your studies at the university?

Other than implementing amplification in the digital domain along the lines suggested by Edward Fisher above, this might possibly be about building a simple class D amplifier using digital logic gates?

Unfortunately, I don't have a detailed schematic for a class D amplifier using digital logic gates. While such a project is conceivable, it would take a while to develop a reliable circuit.

You will need to provide more background information before anyone else can provide more specific help.
