There are two ways of viewing the characteristics of an ideal filter. The first and most common is from the point of view of the frequency domain. This first class of filters would pass without attenuation all frequencies inside certain frequency limits and provide infinite attenuation for all other frequencies. The second point of view is from the time domain. A designer may only be interested in the time response of a filter. This set of notes will present in a basic manner some of the characteristics of mathematical models which have been derived to approximate these two types of filters.
