Hi there,
I'm working on my first electronics DIY project. I have a square PWM signal feeding a simple RC lowpass filter to create a sinusoid, which feeds my 8 Ohm, 0.5 Watt speaker. My speaker is barely audible however, even with 15V pk-pk. I suspect I don't have enough current. Is this the issue, and how can I use a BJT to increase my current?
Thanks,
Ethan
