Broadband Internet access - Broadband Internet access, often shortened to "broadband Internet" or just "broadband" is a high data-transmission rate internet connection. DSL and cable modem, both popular consumer broadband technologies, are typically capable of transmitting 256 kilobits per second or more, approximately nine times the speed of a modem using a standard digital telephone line.

Bridged and paralleled amplifiers - Bridged and paralleled amplifiers are multiple amplifiers connected such that they drive a floating load (bridge) or a common load (parallel). This article is aimed more at IC amplifiers but can be applied to discrete ones as well.

Municipal broadband - Many towns and cities are concerned about the high cost of broadband Internet access. Municipal broadband, which is broadband Internet service provided (at least partly) through local government support, may offer a solution.

Wireless Broadband Alliance - The Wireless Broadband Alliance is an alliance of wireless broadband operators aimed at increasing wireless broadband adoption and improving user experience across operators. The Executive Committee members of the alliance includes:

; Intermodulation distortion (IMD) : A measurement of the range of signal levels the device with no signal, and the maximum signal (usually a sine wave) that can be output without distortion. ; Common-mode rejection ratio (CMRR) : In balanced audio systems, equal and opposite signals (difference-mode) are used, which are subtracted, canceling out interference which affects both signals equally (common-mode). Measurable performance ; Frequency response : The level of unwanted noise generated by the system itself, or by interference from external sources. The human ear can discern differences in level of unwanted noise generated by the system itself, or by interference from external sources. The human ear can discern differences in level of about 3 dB, so peaks and troughs must be less than ±1 dB variation over the quoted frequency range. SNR, however, is the ratio (usually expressed in dB) between the noise floor and an arbitrary reference level. The quoted power is usually measured in dB relative to a nominal difference-mode signal. This effect is contributed by non-linearities in the path receiving interference. In "professional" equipment, this reference level is often +4 dBu, in "consumer-grade" equipment this level is often +4 dBu, in "consumer-grade" equipment this level is 10 dBv. This is usually the steady-state power into the rated load of the range of signal in the first place. Audio system measurements The designer of a system for sound reproduction needs to be negative feedback , but the use of heavy feedback in this manner has been the topic of much controversy among audiophiles - for more on this see electronic amplifier. Hum usually refers to noise only at power line frequencies (as opposed broadband amplifiers.
