FUNCPOLY(U_8) is needed to increase the volume. Open a monitor. This is just an amplifier because the function is "y = 2x". The output becomes twice bigger than the input. If you want M times over sampling, you need an amplifier of M times somewhere. Finally, open a monitor of TXTOUT(U_2). The volume has twice bigger than this. The two times oversampling is complete. You can listen to the sound by Tools -> Play Wave. You can also save the Wave file like following. If you want to save it, double-click on WAVOUT(U_11) and indicate the file name and location. That's it for this class. The process of M times oversampling is ... (1) M times interplator, (2) Low Pass Filter, (3) Amplifier of M times. The first page Back to Index
