[sdiy] DAC....

[James Patchell]

         Hey...did a bit of Synth DIY at work today...believe it or 
not...The project I am working on needs an audio output.  It has to be real 
small and low power.  It has a Cool Runner on the board...so I did up a 1st 
order Delta Sigma modulator in Verilog and to my surprise...it worked.  I 
prototyped it on my Spartan III FPGA board....hooked up a phase accumulator 
saw tooth oscillator to it (also implemented in verilog)...and wow....got a 
saw tooth out of the thing....

         I am trying to decide if I can post the source code on my 
website...technically...it doesn't belong to me :-(......
