Apparatus for suppressing information carrying signals in the power supply conductors of electrical apparatus, comprises a resistor 5 connected in series with one of the conductors, an electrical regulator 8 connected in parallel with the resistor 5 for sensing a voltage drop thereacross, and connected between the conductors for controlling current flow in dependence upon the sensed voltage drop, whereby the current drawn from the power supply 3 is effectively stabilised. Thus current variations in the power supply conductors which correspond in frequency to information carrying signals, and which could result in radiation corresponding to these signals, are effectively suppressed. Load 4 may be a telephone or computer system. <IMAGE> |
