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. |
