Hello,
I would like to build a high-frequency sound generator for 80-90 kHz region. Of course up to 90 from 20.
Can anyone direct me to information regarding such a construction and any other tools needed (compressors..and such)?
Thank you,
Check this option AD9833
0 MHz to 12.5 MHz output frequency range
Do you want to imitate a bat signal?
It's not hard to make an oscillator, especially if you can use a square wave. An LM555 could probably do it or you can use a crystal oscillator with a frequency divider, etc.
But, finding a transducer that can make "sound" at that frequency might be difficult.
Compressors?
This frequency range is mainly the domain of piezo transducers, and usually they are tuned to a small
range of frequencies each.
