Hello guys,
I ever use shield wires for sensitive mics (i.e electerets).
A question that arises is does those wires affect to the signal itself? Does they affect and weak or reduce the signal power of the input signal inside the shield wire too?
Another question is do I need to use those wires on sensitive parts of a device, I mean suppose a very sensitive op-amp and you need to connect a pot as the feedback resistor, do you use those wires if there is a 5 to 6cm or even more distance between the op-amp leads and the pot itself or just you use those wires for inputs?
Thanks
P.s. Is that important putting both ground wires across a shield wire to the ground or just one is enough?
