BlankScott,
The EM field propagates between the capacitors (or capacitor and GND?), but
the capacitor's value is an interesting question. Of course to build a small
and cheap device, lower the capacitor value better. But from the signal
point of view the capacitor has to be big enough to transmit the lowest
frequency-component of the signal in the given impedance environment. So the
question is, what is the lowest frequency needed to reproduce accurately the
signal at the receiver. I think this may be the same problem that was put on
this forum before....how many adjacent zeros (or by the same means ones)
does the signal contain?
George
