Frequency above 20 kHz with Sigma Studio and AD1940?

Hello, i want to expirement with sound in the ultrasonic frequency range, deom about 15 kHz to 40 kHz.

Can Sigma Studio operate in this frequency range, and can i do filtering, ect in this frequency range.
I want to use the AD1940 on the evaluation board EVAL-AD1940MINIBZ-ND , can i use this for my tests?
Also, i am concerned about anti alizing filters on the evaluation board will cut off too low, is that a concern, and can i modify these filters if they are there?

If the above cannot be done, do you have any suggestions for evaluation solutions in this frequency range.

Thank you if you can help me

  • Hello KJBob,

    First of all, thank you very much for responding so fast to my question, and also for the very informative answer.
    Can i ask one more question?

    What about Sigma Studio, if i use the ADAU1701MINIZ board, will i be able to define filters and other functions, in Sigma Studio, above 20 kHz?
    The reason i ask is that when i look at many examples, is is like the graphs,  equilizer functions, ect, stops at 20 kHz, but will Sigma Studio let me "play around" above 20 kHz, if i choose lets say 96 kHz sampling frequency in the ADAU1701MINIZ board?

    Best regards
