    An electronic device that does not use any amplification circuits. Applied mostly to filters, it describes a cut-only design, and because of this, passive circuits are less prone to distortion. In practice, even though a filter is described as passive, it may none the less have make-up gain circuitry at its output to compensate for the loss in power that cutting can cause.
