Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. A distributed
element filter is an electronic filter in which capacitance, inductance
and resistance (the elements of the circuit) are not localised in
discrete capacitors, inductors and resistors as they are in conventional
filters. Its purpose is to allow a range of signal frequencies to pass,
but to block others. Conventional filters are constructed from inductors
and capacitors, and the circuits so built are described by the lumped
element model, which considers each element to be "lumped together" at
one place.
