What is the chemistry behind making butter?

To make butter, the cream is agitated (stirred up) so that the fat molecules get shaken out of position and clump together. Eventually, after enough agitation, the fat molecules clump so much that butter forms.

What is the use of butter function in Matlab?

butter uses a five-step algorithm: It finds the lowpass analog prototype poles, zeros, and gain using the function buttap . It converts the poles, zeros, and gain into state-space form.

How does a Butterworth filter work?

The Butterworth filter is a type of signal processing filter designed to have as flat frequency response as possible (no ripples) in the pass-band and zero roll off response in the stop-band. Butterworth filters are one of the most commonly used digital filters in motion analysis and in audio circuits.

What is butter in science?

butter, a yellow-to-white solid emulsion of fat globules, water, and inorganic salts produced by churning the cream from cows' milk. Butter has long been used as a spread and as a cooking fat.
