[NSRCA-discussion] beep tones

[Dennis Bodary]

Do you guys just come up with these questions just to make me feel stupid?It really does not take much anyway.Not only do i have no idea what produces the tone.
But i have no idea what so ever what a nano oscillator circuit is much less a nano piezo circuit.

I have a question that came up at ther flying field yesterday.The query was: What produces the arming tone and the cell count tones that are audible when the battery is plugged in to an electric motor powered model?
 There were guys that were adament that the tones were produced by the currentsurging through the motor. There was confusion due to the fact that no visible speaker could be observed.
 I felt that there had to be nano oscillator circuits in the esc working some kind of anano piezo circuit generating the required tones, but I really had no idea. Can somebody please clear up the confusion, ? anybody,? Peter???
 Thanks  Georgie
