Question
Draw the circuit diagram of a zero-crossing detector using a 339 comparator stage with $\pm 12-\mathrm{V}$ supplies.
Step 1
First, we need to set up the LM339 comparator with the ±12V supplies. Connect the positive supply (+12V) to pin 3 (Vcc) and the negative supply (-12V) to pin 12 (GND). Show more…
