In order to restore the galvanic safety path of the signal wiring up to a certain level, it is possible to connect a 1 00 O H M S 1W resistor parallel with the 1 00nF capacitor . The isolation of the low frequency ground loop is partly canceled by this resistor, but the reduction of the induced noise can still be sufficient while at the same time s ...
