The operating frequency by simulation is 720Hz.And define what you mean by "sound", in terms of frequency. 12kHz is sound to my kids, but not me.
Oops, cross post.
If that is the case, you need to tell us what is unique about the sound of the frog that be isolated from other sounds.Thanks to you all,
I want to create a project that can only detect the sound of a frog that can output to a servo motor. If the sound detected is not a frog voice the circuit does not operate.
No , you can't use frequency - magnitude plot only. Timing is very important as well. What you need is frequency-time-magnitude, they called it's waterfall spectrogram.I uploaded some spectrum graph. Can you tell me what type of approach and design that I need to do.
Sorry everyone if i cannot explain it more clearly and specific. That's why I'm here to seek help!. thank you all
