Chirp Pattern (Not in Base Package)

Generates an array containing a chirp pattern. Details

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.
f2 is the ending 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.

Chirp Pattern Details

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.
