I am going to make some audio signal processing on ultrasonic audio signals, mainly in the frequency range from 20 kHz to 40 kHz.
I would like to do some preliminary filtering expirements, and i was planing to use the AD1940 SigmaDSP Using the EVAL-AD1940MINIBZevaluation board and the Sigma Studio package.
Is this possible for me, i will the above configuration work at frequencies above 20 kHz, and can i define filters in Sigma Studio above 20 kHz, and is the AD1940 fast enough?
Also, i am concerned if there are anti alizing filters in the analoug input on the evaluation board, the will limit my audio band with?
Thank you very much
