What is Autocorrelation?

Uses 3 examples to explain Autocorrelation, and provides an intuitive way to understand the function in terms of Average Shared Directed Power.

"Average Shared Directional Power" is this night's take to bed message; thanks for your amazing explanations professor 🙏

Autocorrelation well explained. Brief and to the point. Thank you for posting.

[osamahabdullah]

what a wonderful explanation, thanks a lot

Hey Prof Iain, so can i understand autocorrelation as a way to show the power information of a signal instead of really a correlation?

[schlast]

well. I am here to try to learn autoorr([1 2 3 4 5]). I still have no idea what it is supposed to be.

Autocorrelation can be indeed used to discover signals that exhibit pseudo-random noise characteristics, like CDMA

Is there any digital communication scheme that actually use this concept ?

[Will-bxwz]

can you explain why we need to take complex "conjugate" E[Xt1, Xt2*] to calculate correlation? why won't E[Xt1, Xt2] (without conjugation) work?

[rnpradios]

Your videos are great!

Can please make a video on zadouff code

So valuable content that is superficially similar to the Convolution Theorem but as you present with differnt interpretation. For me this is can be so creating sample of water storage as civil engineer research. First of all thank you for 3 samples with important concept. All I see is full of knowledge and it can be so helpful - how you present type of signal in another time in 3 graphs; also how you present squere voltage with R>0 in another direction and imply in time average. Brilliant solved problem in theme summer and winter. We are concerned mostly with functions and manipulations like this to solve problem, but easy algebra is the key of success. This example will clearly show first path of building construction of the reservoirs downstream and upstream intended to isolate the water zones of the reservoir.

"Voltage squared is power"
Ummm, actually it's V^2/R 🤓
