Abstract
An electronic system denoising device, includes: a power source, a first signal processing unit, a second signal processing unit and an isolating transformer. The power source is coupled to the first signal processing unit, and to the second signal processing unit via the isolating transformer, and supplies power to the first signal processing unit and the second signal processing unit. The first signal processing unit includes a first signal output end and a first grounded end, and the first signal output end outputs data signals to the second signal processing unit. The first grounded end is coupled to a first ground wire; the second signal processing unit includes a second grounded end coupled to a second ground wire. The electronic system denoising device, via the isolating transformer, avoids impact to the second signal processing unit from ground noise caused by the return current of the first signal processing unit.
