Hello,
I am going to see the output waveform of class B amplifier. First of all, I tested this circuit
For low frequency (200Hz-200Khz) I see this waveform at the output.
But by increasing the frequency value up to 2Mhz, I see the input frequency exactly at the output without any disturbance( I see that It has low disturbance and some undesired frequencies that I can't see them on the oscilloscope without any FFT function) while the FT of transistor is more than 100Mhz.
So I need to know why I see the same waveform in output.
