Introduction, definition of terms, Qamp;As

In the operation of electronic systems and circuits, the basic function of a filter is to
selectively pass, by frequency, desired signals and to suppress undesired signals. The amount
of insertion loss and phase shift encountered by a signal passing through the filter is a
function of the filter design.

Constant impedance IF bandpass filters improve circuit performance

Double-balanced mixers are normally very wideband. When used as down converters, the sum and difference frequencies are of equal amplitude. Filtering is essential to remove the sum frequency.
