Attenuation: The loss of signal energy due to absorption, reflection, or diffusion during transmission.

Foliage Attenuation: Reductions in signal strength or quality due to signal absorption by trees or foliage obstructions in the signal's line-of-sight path. For example, 800 MHz systems are seldom deployed in for . . . View Full Definition

Sound Attenuation: Sound proofing a wall or subfloor, generally with fiberglass insulation.

Attenuation (Of Light): Diminution of light intensity; explained, in the ocean, in terms of absorption and scattering

Differential Reflectivity (ZDR): Ratio between the reflectivity of a horizontal polarised pulse and the reflectivity of a vertical polarised pulse. Zdr depends on the asymmetry of the shape, the orientation and the falling . . . View Full Definition

Return Loss: The ratio of signal power transmitted into a system, to the power reflected or returned. This is like an echo that is reflected back by impedance changes in the system. Variation in impedanc . . . View Full Definition

Chebyshev Filter: A filter that has some ripple in the pass-band but has an initial attenuation slope which is steeper than a Butterworth filter.
