Decibel — This article is about the ratio of measures. For sound or acoustic level, see Sound pressure. For other uses, see Decibel (disambiguation). Attenuation chart of an RG 6 Coaxial cable, measured in decibels per 100 feet of cable The decibel (dB) is … Wikipedia
Decade (log scale) — One decade is a factor of 10 difference between two numbers (an order of magnitude difference) measured on a logarithmic scale. It is especially useful when referring to frequencies and when describing frequency response of electronic systems,… … Wikipedia
Bode plot — ; the straight line approximations are labeled Bode pole ; phase varies from 90° at low frequencies (due to the contribution of the numerator, which is 90° at all frequencies) to 0° at high frequencies (where the phase contribution of the… … Wikipedia
Scattering parameters — or S parameters are properties used in electrical engineering, electronics engineering, and communication systems engineering describing the electrical behavior of linear electrical networks when undergoing various steady state stimuli by small… … Wikipedia

Butterworth filter — The Butterworth filter is one type of electronic filter design. It is designed to have a frequency response which is as flat as mathematically possible in the passband. Another name for them is maximally flat magnitude filters.The Butterworth… … Wikipedia
Okumura Model — The Okumura model for Urban Areas is a Radio propagation model that was built using the data collected in the city of Tokyo, Japan. The model is ideal for using in cities with many urban structures but not many tall blocking structures. The model … Wikipedia
