We have a circuit that creates square wave at several KHz. When there is no interference, the waveform is good. But when an external noise source is online, like a motor driver, even if it is at a great distance, the waveform is distorted highly. There is a noise component in the supply that powers the circuit that produces the waveform. We could not prevent the noise that comes through the power line. What do you offer? The supply scheme is similar to the one that is in the drawing.
