```cs
public sealed class FourierFrequency : IStorable
```

A single element in a Fourier frequency space.

## Constructors

- [FourierFrequency](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.functions.standard.fourierfrequency/ctor.md): (2 overloads) Create a new frequency element.

## Properties

- [Amplitude](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.functions.standard.fourierfrequency/amplitude.md): Gets the amplitude for this frequency.
- [Frequency](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.functions.standard.fourierfrequency/frequency.md): Gets the intrinsic frequency.
- [IsZero](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.functions.standard.fourierfrequency/iszero.md): Gets whether this frequency is considered zero.
- [Normalised](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.functions.standard.fourierfrequency/normalised.md): Gets the normalised frequency (the intrinsic frequency multiplied by 2pi).
- [Phase](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.functions.standard.fourierfrequency/phase.md): Gets the phase offset for this frequency.
