I am using below scheme for generating different voltages using transformer.
T1 transformer generates 15V and 48V ac and then rectified by AC-DC converter to generate different DC voltages (12V_Op amp Supply, -12V_Op amp supply, 16V_Logic, 38V_Constant Current Source) for my circuitry. But transformer is generating noise which is hampering ADC circuit and variation observed in ADC.
What techniques I can ensure to eliminate noise from transformer, please someone guide.
Thanks in advance.
