Hello all,
I am building a phase correlation meter using an LM3914 to drive an LED bar display. Everything is working correctly besides the LM3914. The LEDs light but they slowly cycle one at a time all the way up and all the way down the bar as if there’s a step time. I have no clue why this is happening or where the step time would be coming from considering the circuit was working completely fine a few days ago. I am using two equal sine waves as the inputs for the phase meter and as increase the frequency of the sine waves the step time of the LEDs seems to increase as well. Why is this happening and how can I fix it?
