My original post suggested a possible application which incorporated the use ofa bandpass filter for synthesizing a 60Hz signal for off grid power:
"...we discussed inverter design and I suggested a 60Hz square wave with a fourth order band pass filter to capture the fundamental frequency and
Sheesh Mike why the hostility?
It sounds like you don't really want any help.
I am sorry if my humor comes off like what do you call it?
Hmmm? Please stop trying to be profound and get to the point.
You might reread your first post in this thread. You never stated a
point to begin with. I have no

Hi Mike
So would I.
Did you?
The filter has less to do with sine wave synthesis and more to do
with ensuring a clean signal.
Of course, this is basic electronics.
Which is probably why Kirk said it is very lossy. To turn away a
signal is in itself loss unless you have some way to feed it back

Just proof I need to answer email after I sleep.
The idea in my mind was you were pumping a squarewave through a lowpass filter to make an approximation of grid power.
I see you are just using this as a control signal.
Lancaster wrote some articles about approximating a sinewave
I posted this in another group and thought it might also benefit some of you since it's logical to think that some members are off-grid and synthesizing their own power signal.

OK Soare you going to explain why or just leave me hangin'?

Hi I have a bit of electronic knowledge albeit a tad rusty.
I followed your link but without knowing what you are trying to do I
am at a loss as well.
What are you inverting?
Are you simply changing DC to AC?
If I was trying to do this the first thing I would do is hit the
standard circuit design
Brian,
"Are you simply changing DC to AC?"
Yes.
"If I was trying to do this the first thing I would do is hit the standard circuit design books."
So would I. The filter has less to do with sine wave synthesis and more to do with ensuring a clean signal. There is also the added bonus of
