Speech generation using PWM..MC9S08QE8

Hi All,

 

I am looking to digitise voice data at 8kHz 8 bits (using the on board ADC), store it and reproduce it using the PWM facility of the processor. I have no experience of this as I have always used a DAC. Is it feasible to do at 8kHz 8 bit resolution? Also how do I work out what clock rate to use etc? I would also appreciate some pointers to  the the use of PWM for audio generation. Are there any application notes available?

 

Thanks in advance.

Steve
