Filters that are typically Notch (Channel Removal), Band Pass (Pass Specific Range) or Pass Band (Pass all BUT a Specific Range). If Installing a Filter that will affect an entire Network, it is best to install at Amplifier Input versus Output. Notch Filters are part of but not completely effectual alone for Channel Elimination. Common Band Pass and Pass Band Filter examples are Diplexers and Separators. Very Few Filters handle Voltage Pass, be Carefull to ascertain their Capability prior to Use.
