samples is the number of samples of the Chirp Pattern. The default is 128. |
![]() |
amplitude is the amplitude of Chirp Pattern. The default is 1.0. |
![]() |
f1 is the beginning frequency of Chirp Pattern in normalized units of cycles/sample. |

Chirp Pattern is a signal with frequency ramping from f1/fs to f2/fs, where fs is the sampling rate. |

error returns any error or warning from the VI. Refer to Signal Processing Error Codes for more information about these conditions. |
If the sequence Y represents Chirp Pattern, the Chirp Pattern VI generates the pattern according to the following formula.
for i = 0, 1, 2, , n - 1
where A is the amplitude, a = 2 (f2-f1)/n, b = 2
f1,
where f1 is the beginning frequency in normalized units of cycles/sample, f2 is the ending frequency in normalized units of cycles/sample, and n is the number of samples.
