Hye,
1) I want to attenuate the EMI effect on my circuit.The mobile phone signal distract my earphone where "tut" like pulse sound occur.The only method that i know is shielding.Shielding mean i need to cover up m circuitry using aluminum foil.It not changing any circuitry design.I need atleast some modification on my circuit to attenuate EMI effect.Is there any additional component should be add on any audio circuit to attenuate the EMI effect especially cause by mobile phone signal.
2) There is noise on my circuitry.I guess it is a white noise.However,another possibility is my condenser mic is pick up noise.Is there any way to reduce the noise or is there any way to produce a clean sound on for analog circuit?
I attached along my circuit concept.
