noisebw
Equivalent noise bandwidth of digital lowpass filter
Syntax
Description
returns the two-sided equivalent noise bandwidth of a digital lowpass filter in Hz. Specify the filter coefficients in descending polynomial powers by numeratorbw
= noisebw(num
,den
,N
,Fs
)num
and denominatorden
. InputN
is the number of samples of the impulse response.Fs
is the sampling rate for the filtered signal. For more information on the two-sided equivalent noise bandwidth computation, seeAlgorithms.
