Power Spectral Density

A power spectral density spectrum helps quantify broadband signals consistently independently of the spectral resolution used. More information on the Simcenter Testing community: community.sw.siemens.com/s/ar...

Great introduction. It explains things to me. Thank you!

[@kidflix8562]

Great and fun explanation! Thanks!

That glass analogy is epic. I am showing this to my mates.

The metaphor is very good, very vivid and wonderful

[@jesseli9868]

Enjoyed the metaphor, it makes the concept very intuitive yet you can still tell it has its roots in the underlying mathematics.

[@alirezasadeghi2560]

Perfect , Best explanation

[@jolan6616]

Very clear, thank you

Can you make one video using audacity too? I want psd curve in it

[@evanparshall1323]

Great video. The only thing that should be explained more clearly is signal resolution. I had to look that up. In this video, higher resolution means it takes shorter time for the signal to be measured. The sampling rate is fixed for all signals in this video. Resolution = Sampling Rate (fixed in this video) / Duration of signal (number of samples)
