• During analog to digital conversion with PIC the noise occurs
• The problem is current from the supply because it does not absorb enough the noise ,We have developed a circuit for it (together with my brother) ;-)
• Circuit transformer, capacitor and diode is comprised of. Operating logic, capacitors absorb noise.
• Three output transformer should be selected. Because the output  (+9v)  (GND)  (-9v)
• IMPORTANT! – Works with PIC s 5v circuit voltage of 5 volts should regulate, or PIC will be damage!!!.(9v>5v regulator circuit)
