I think it needs to be fairly good as I intend to mix two of these signals together, 14 KHz and 14,25 KHz in order to get the 250 difference frequency. The medium I will be passing the signals through is human flesh and the is not much reactance there to clean things up.Phasor said:Do you need a good quality wave, or just a rough wave?
Thanks a lot kinjalgpkinjalgp said:Colpitts Oscillator can solve your purpose.
It can produce fairly good sine waves at frequencies around 10kHz-1Mhz. Have a look at the schamatic.
The output of this oscillator when fed to a step-up transformer will produce high voltage sine-waves. The inductor used can be of variable reluctance type to vary the freqyency. Also you can use variable capacitor.
