# RF Filter design equations

radio frequency filter design equation

A generalized set of equations can be formulated for the design of first-order and secondorder

low pass and high pass filters. A specialized set of equations is devised for designing

parametric biquad EQ filters.

As with any other filter design procedure, the desired characteristics of the filter are to be

made available. The parameters governing the desired filter properties are as follows:

· Filter cut-off frequency i.e. edge or corner frequency (fc).

· Sampling rate (fs).

· Q factor

· Boost/Cut gain value at fc
