In commutative algebra, the prime spectrum (or simply the spectrum) of a commutative ring R is the set of all prime ideals of R, and is usually denoted by ; [1] in algebraic geometry it is simultaneously a topological space equipped with the sheaf of rings.

Unlike the Itakura–Saito distance, the log-spectral distance is symmetric. [2] In speech coding, log spectral distortion for a given frame is defined as the root mean square difference between the original LPC log power spectrum and the quantized or interpolated LPC log power spectrum.
Spectral efficiency, spectrum efficiency or bandwidth efficiency refers to the information rate that can be transmitted over a given bandwidth in a specific communication system. It is a measure of how efficiently a limited frequency spectrum is utilized by the physical layer protocol, and sometimes by the medium access control (the channel ...
The optical spectrum is sometimes considered to be the same as the visible spectrum, but some authors define the term more broadly, to include the ultraviolet and infrared parts of the electromagnetic spectrum as well, known collectively as optical radiation. [1] A typical human eye will respond to wavelengths from about 380 to about 750 ...
The Spectrum (later known as CoreStates Spectrum, First Union Spectrum and Wachovia Spectrum) was an indoor arena in Philadelphia, Pennsylvania. The arena opened in September 1967 as part of what is now known as the South Philadelphia Sports Complex .
A spectrum disorder is a disorder that includes a range of linked conditions, sometimes also extending to include singular symptoms and traits.The different elements of a spectrum either have a similar appearance or are thought to be caused by the same underlying mechanism.
