WebThe least you can do is to add a low-pass filter (10 Hz or so), to average the input signal so the BJT conduction remains at the same level all along the input signal's wave. For another thing, you applied the signal directly to the base, with no current limiting resistor. That BJT is now a voltage follower (common collector topology), which ...
