frequency_bin_width Function

public pure elemental function frequency_bin_width(fs, n) result(rst)

Computes the bin width for a discrete frequency spectrum based upon the data sample rate.

The frequency bin width is computed as follows.

$$\Delta f = \frac{f_{s}}{2 \left(m - 1 \right)}$$

where m is computed via compute_transform_length.

Arguments

Type	Intent	Optional	Attributes		Name
real(kind=real64),	intent(in)			::	fs	The rate at which the signal was sampled. The units of this value will be the units of the output.
integer(kind=int32),	intent(in)			::	n	The signal length (length of the signal put forth to the Fourier transform).

Return Value real(kind=real64)

The frequency bin width.
