My customer asked me some question on Figure29 in the LTC2500-32 datasheet.
1. what is output sample number(horizontal axis)?
2. what does D1(n) mean? DF=1?
3. what is theDF setting for LTC2500-32 OUTPUT SAMPLES DOUT(k) ?
4. would you expalin what SINC1 FILTER OUTPUT D1(n) line and x shows?
and why ithe vertical value is 3/4 when the horizontal value is 1 and the vertical value is 2 when
the horizontal value?
does this mean it's 2 stage FIR filter with the first coefficient is 3/4 and the second coefficient is 1/4?
