  • EMI - smart meters do a lot of pulsing - effects on PI?

    I thought this might be interesting:

    The pulsing is 2ms or so as far as I have read and way more often than I thought.

    I am assuming that all pulsed signals will effect PI perfomance,
    no matter what the base frequency. Is that correct?

    If so, could we or Qiaozhi or Carl make a sticky which has a:

    - collection of possible EMI sources to look out for in urban settings (low distance range) and in house.
    - sources that are more far reaching (I think Ferric Toes mentioned Digital TV broadcasts or something along these lines)

    which can drive PI builders nuts?
