Sampling vs. data rate, decimation (DDC) and interpolation (DUC) in high-speed data converters

See all videos in the TI Precision Labs - ADCs Training Series

This video is part of the TI Precision Labs – ADCs curriculum.  This
video covers Sampling Rate vs Data Rate, Decimation (DDC) and Interpolation
(DUC) Concepts in High Speed Data Converters.

These videos help us educate ourselves a lot while also making us love TI. I guess, that was the point.

Thanks for the clear explanation. It would be great to have another video on how decimation improves spectral performance .

Decimation is the digital version of taking a SWAG of the bit(s) between the bits of the sample. If it adds 1 bit, the frequency is doubled. 2 bits, it is doubled twice, and 3 bits, it is doubled 3 times, etc. It is a rather simple code. No slight intended.

hi sometimes we have a rf signal that it's not repeatitive like a sound wave how can we downconvert this signals to sampling with low sample rate analog to digital converters? is there any way?

Why is Mr. Hawking narrating a TI video?

[rachelcawley]

You start the video by explaining the differences between sample rate and data rate...and then in later slides you use the terms in conflict with the words on the slides, which is confusing.

Extremely confusing, this video needs a major haul. When discussing JESD204B data converter, it says "Interpolation must be used to reduce the data rate", I hate it.
