squarewave

Hi, I'm having issues with a IR2110 based MOSFET driver circuit, specifically IRLZ44N, the signal comes in from my signal generator at 5vpp, then goes into pin 12 on the IR2110 and reaches it correctly, pin 11 and 10 to GND, pin 9 to pin 3 on the 7805 5v regulator, pin 3 is vcc so it goes to the...

I know it is stupid, but I keep struggling with my problem. I have a Square wave 24DC + 9 AC. What happens is that theres is some communication protocol on top of that. I need to power some electronics with that line, but the Ups and Downsof the wave keep charging and discharging the coupling...
