Fixed Multiplier Upsampling
Hi.......the main point of upsampling is to make the digital filter (part of the DAC) easier to design. When you upsample, you can inject zeroes or random data into the data stream, it doesn't change the end result. Strange but true; you'll need to read a book on signal processing to understand why things work that way. Anti-aliasing is different... if you filled in every second pixel automatically with black, an antialiased image would look terrible. Whatever efforts the programmer put in, I still believe the hardware design should also be improved by the manufacturers. I can't see the good pcb assembly and good quality components. These factors add the external noise and cannot be mitigated in firmware design.
