Hi all, i have a quick question concerining sampling frequencies. I have the ADC of my microcontroller set up with the maximum sampling frequency of 15 kHz but the programme uses timer interrupts to fill an array with ADC values at a rate of around 2 kHz.
My question is if i were to design an anti aliasing filter for the system would i need to use the sampling frequency of the ADC or that of the timer interrupt system. Any help would be greatly appreciated. Thanks in advance.
