sine wave generator

Hi to all, i want to generate high precision,low frequencies sinusoidal signals (50,80 and 180 hz) trough my altera cyclone4 (vhdl code) with the PWM technique. I've started to do some tests, i...

Maybe the TE has a look at the DDS basics. Of course any frequency can be generated this way, taking into account the limits of DDS. Regarding PWM output this is another issue. PWM limits the precision of the generated wave.
