I am trying to figure out how does this circuit works.. In my fist impression it is a damped system like Velkonivich's two stage mechanical oscillator. Damping happens in L3.. It is specially selected.. But HOW?
I want to calculate oscillation frequency of this Colpits. If it is still Colpitts..
Doctor always mentioned UWB, today I have used FFT in my scope and saw peaks from sec15 on the tower... It seems that square wave damping opens up all ports (resonant frequencies of L3) and communicate with infinitum.
All Please comment on my above suggestions.. I will be sick on thinking of this SEC theory..
Thanks..
