center_freq()

Returns the center frequency at the specified level as a real number.
Syntax
fc = center_freq(Data, ReferenceBW)

Arguments

Name	Description	Range	Type	Required
Data	data (usually gain) to find the center frequency	(-∞, ∞)	complex	yes
ReferenceBW	a single value representing the reference bandwidth	(-∞, ∞)	real	yes

Examples

This example assumes that an S-parameter analysis has been performed.
fc3 = center_freq(db(S21), 3)
returns the center frequency using the 3dB point as reference.

Notes/Equations

This function returns the center frequency of a filter response. Linear interpolation is performed between data points. The function uses an iterative process to find the bandwidth on non-ideal responses. The data can be from 1 to 4 dimensions.
