Hi,

I have a doubt in the exercise BOOSTXL-AUDIO_430BOOST-SHARP96_FFT_FIR_LEA_MSP430FR5994 and in general with the ADC. The ADC has integrated an antialiasing filter?

Thank you for your time.

Marcos.

Hi Marcos,

By looking at the schematic for the BOOSTXL-AUDIO boosterpack, you will see that there is an RC low pass filter acting as an anti-aliasing filter right after the input signal passes the microphone amplifier and before it gets to the ADC.
