# AnalyzedResult property

Class: rfckt.delay
Package: rfckt

Computed S-parameters, noise figure, OIP3, and group delay values

## Values

rfdata.data object

## Description

Handle to an rfdata.data object that contains the S-parameters, noise figure, OIP3, and group delay values computed over the specified frequency range using the analyze method. This property is empty by default.

The analyze method treats the delay line, which can be lossy or lossless, as a 2-port linear network. It computes the AnalyzedResult property of the delay line using the data stored in the rfckt.delay object properties by calculating the S-parameters for the specified frequencies. This calculation is based on the values of the delay line's loss, α, and time delay, D.

$\left\{\begin{array}{c}{S}_{11}=0\\ {S}_{12}={e}^{-p}\\ {S}_{21}={e}^{-p}\\ {S}_{22}=0\end{array}$

Above, p = αa + , where αa is the attenuation coefficient and β is the wave number. The attenuation coefficient αa is related to the loss, α, by

${\alpha }_{a}=-\mathrm{ln}\left({10}^{\alpha /20}\right)$

and the wave number β is related to the time delay, D, by

$\beta =2\pi fD$

where f is the frequency range specified in the analyze input argument freq.

The analyze method uses the S-parameters to calculate the group delay values at the frequencies specified in the analyze input argument freq, as described in the analyze reference page.

## Examples

Compute S-parameters, noise figure, OIP3, and group delay values:

```del = rfckt.delay;
analyze(del,[1e9,2e9,3e9]);
del.AnalyzedResult
```
