    Hi Dave,

    I am new to the forum and just started my studies in Electrical Engineering. The DC component is something I have been seeing alot of initially but I am having difficulty understanding it.
    When you say the A is the DC component of the function x(t) = A+Bsin(pieft) can you give me an example equation of this? I would really appreciate it.
    Oh and also how did you do the pie like that with the keyboard?

    Actually, it is incredibly easy to filter, so it isn't as big a problem as you state. Most AC power is converted to DC, which filters it from the get go.

    A lot of applications don't care, light bulbs and fluorescent lights, for example.

    Where it does matter, conditioners are available everywhere, or you can roll your own.

    I don't think I've heard to dirty power referred to as toxic before. I tend to think of dirty power as something that browns out, I don't worry about what is riding on it.

    I think a brand new spammer was just squashed.
