Definitions for "Low Pass Filter"
A filter whose frequency response remains flat up to a certain frequency, then rolls off (attenuates signals appearing at its input) above this point.
(Inductor or Choke) Allows more signal to pass through the lower the signal gets - ideal for a sub.
A processing module that attenuates high frequencies more than low frequencies (or boosts low frequencies more than high frequencies.)
a "key" component for proper RF distribution where modulators are involved as it prevents broadcasted information from interfering with the "in house" modulated channels
