In this section we consider circuits that form filters. These are circuits that will attenuate signals at certain frequencies and allow signals at other frequencies to pass but initially we will discuss the decibel scale
 

The Decibel Scale This page introduces the use of Decibels
The Low Pass Filter This page discusses circuit that attenuate signals with high frequencies.
The High Pass Filter Circuits that attenuate signals with low frequencies
The Band Pass Filter A Circuit that will attenuate any signal that does not have a frequency between two limits
The Band Reject Filter A brief look at a circuit that will attenuate any signal that has a frequency between two limits.
