1. An electronic apparatus comprising:
an electronic board on which are placed an analog subassembly and a filtering unit, the analog subassembly comprising one or more analog components;
wherein the analog subassembly is protected by shielding placed on one side of the electronic board,
wherein the filtering unit is placed on the side of the electronic board on a signal path electrically connected to the analog subassembly,
wherein the filtering unit comprises a capacitive component placed under the shielding and connected to an analog ground,
and wherein the filtering unit further comprises a filtering component placed on an input to the filtering unit in series with the signal path on passing through the shielding or in an immediate vicinity of the shielding,
wherein the electronic apparatus further comprises a power supply/digital block placed on the electronic board, where the power supply/digital block comprises a digital subassembly and/or a power supply subassembly, wherein the digital subassembly comprises one or more digital components, and the power supply subassembly comprises one or more electric power supply components for the analog subassembly, wherein the filtering unit is placed between the analog subassembly and the power supply/digital block.
