Signal Generator by Duration function Exercise

Hey, someone maybe knows how I can do this exercise?


Using the Signal Generator by Duration function (multiple use of the function)
generate the following waveform:

y(t) = 10 sin ( ωt) + 10/3 sin ( 3ωt) + 10/5 sin ( 5ωt)

for t from 0 to 2π, where ω = 2π / T, and T is the period of the first harmonic.

Present the signal generated in the form of samples graphically on the XY object Graph. The X axis represents time - find the vector X values ​​based on the following data: number of samples 512 (one period of the first harmonic), sampling rate 25.6 kHz.

example of program:




I tried to make it this way, but I don't think it works correctly

The waveform looks good to me, what is the question again?

Hi michal,


unfortunately you forgot to attach your VI! (We cannot debug/edit/run images with LabVIEW…)


Your image does not fit to your formula:

  • you don't add any sinewaves,
  • you don't have a range of 0…2pi,
  • there are no scaling factors of 10, 10/3, 10/5

Mind to share your code after adapting to your requirements?

Best regards,
