Bandwidth of One Pole
A typical formula relating bandwidth (in Hz) to the pole
radius is

(9.7) 
where denotes the sampling interval as usual. Solving for
gives
In
§C.6 (see also §10.1.3), it is shown that is
the 3dB bandwidth or halfpower bandwidth,
in the limit, as the sampling rate goes to infinity.
