AnalysisLibErrType Chirp (int numberOfElements, double amplitude, double beginningFreq, double endingFreq, double chirp[]);
Generates an array that contains a chirp pattern. Chirp generates the output array x according to the following formula:
| where | |
|
|
| and where | f1 is the beginning frequency in cycles per sample |
| f2 is the ending frequency in cycles per sample |
| Input | ||
| Name | Type | Description |
| numberOfElements | integer | Number of elements to generate in the chirp signal. |
| amplitude | double-precision | Amplitude of the resulting chirp signal. Default Value: 1.0. |
| beginningFreq | double-precision | Beginning frequency of the resulting chirp signal in normalized units of
cycles/sample. Default Value: 0.0. |
| endingFreq | double-precision | Ending frequency of the resulting chirp signal in normalized units of cycles/sample. Default Value: 0.5. |

| Name | Type | Description |
| chirp | double-precision array | The generated chirp pattern. |
| Name | Type | Description |
| status | AnalysisLibErrType | A value that specifies the type of error that occurred. Refer to analysis.h for definitions of these constants. |
