# 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 ```
