BFDSP & AD73311L

Question asked by AlonIs on Dec 26, 2011

I Have an 4 AD73311L codec conncted to BF547 . 2 pairs in cascade .one pair to the primary Sport and the second to the secondary Sport.

the ADC is sampling in 64k. and I'm working in 16k. each 4 samples of the all 4 ADC ,a buffer of 16samples is filled ,and called to an interupt in the processor. I'm working only with the latest sample of each one. working this way is adding me a low pass in the sampled signals .

If I will take earlier 4 samples from the 16 length buffer the low pass will disappear.

I don' want to solve this problem that way(RT considerations) . How can i solve it wiyhout adding a delay to my system ?

 

thank in advance

Alon
