Wells specified that the black smoke consists of an unknown element that shows four blue lines in a spectrum analysis.

He then worked in the electronics industry on laboratory instruments for spectrum analysis.

A "full spectrum" analysis considers all the "peaks" within a spectrum.

The spectrum analysis is based on the principle that certain eigenforms and frequencies of the tire/wheel assembly are highly sensitive to the inflation pressure.

Investigate the intriguing science of spectrum analysis.

It was the first element discovered by spectrum analysis, and is the most strongly basic and electro-positive substance known.

Without spectrum analysis, identification would not be possible.

Common applications of Bartlett's method are frequency response measurements and general spectrum analysis.

Schoellhamer, D. (2001) "Singular spectrum analysis for time series with missing data".

He wouldn't know a spectrum analysis if it smacked him in the face.
