Hi there,
I have some noise in a circuit I need to get rid of. My
circuit is next to a high voltage switching unit operating at 100Hz.
My circuit is picking up a burst of noise at this frequency. I can't
move my circuit futher away. All the cables are ground-shielded co-ax.
Is there some way I can block-off this noise?
Thanks
Gareth |

Is your circuit shielded? How?
Is your circuit connected to the offending unit?
At what frequencies does your circuit operate? Can you install filters
in either unit? Do you believe the noise is broad-band high-frequency
noise (well above 100 Hz)?

It might be helpful if you defined what you mean
by "my circuit".
