Is there a way to get rid of voltage clippings across a load, so that the voltage output waveform across it is a sine wave?
So, we've been assigned to simulate a circuit to drive an 8ohm 0.25 watts speaker/load with a 3V voltage supply (DC) and a test input of 300mV peak-to-peak, 1kHz zero-offset sine-wave. (No additional ...
