InFrequencyRange(TouchstoneData, double, double)

Filters frequency points to a specific frequency range (inclusive).

public static TouchstoneData InFrequencyRange(this TouchstoneData data, double minHz, double maxHz)

Parameters

data TouchstoneData

The Touchstone data.

minHz double

The minimum frequency in Hz.

maxHz double

The maximum frequency in Hz.

Returns

TouchstoneData

A new TouchstoneData with filtered frequency points.

MaxFrequencyHz(TouchstoneData)

Gets the maximum frequency in Hertz.

public static double MaxFrequencyHz(this TouchstoneData data)

Parameters

data TouchstoneData

Exports the Touchstone data to CSV format.

public static void ToCsv(this TouchstoneData data, TextWriter writer, FrequencyUnit frequencyUnit = FrequencyUnit.Hz, DataFormat dataFormat = DataFormat.DecibelAngle)

Parameters

data TouchstoneData

The Touchstone data.

writer TextWriter

The text writer to write CSV content to.

frequencyUnit FrequencyUnit

The frequency unit for the output (default: Hz).

dataFormat DataFormat

The data format for the output (default: dB/angle).
