| Effective heightIn telecommunication, the term effective height has the following meanings: 1. The height of the center of radiation of an antenna above the effective ground level. In low- frequency applications involving loaded or nonloaded vertical antennas, the moment | Effective input noise temperatureIn telecommunications, effective input noise temperature is the source noise temperature in a two- port network or amplifier that will result in the same output noise power, when connected to a noise-free network or amplifier, as that of the actual networ | Effective mode volumeFor an optical fiber, the effective mode volume is the square of the product of the diameter of the near- field pattern and the sine of the radiation angle of the far-field pattern. The diameter of the near-field radiation pattern is defined here as the f |

| Effect of taxes and subsidies on priceTaxes and subsidies have the effect of shifting the quantity and price of goods. A tax on the production of goods will shift supply to the left; when other things remain equal, this will increase price paid by the consumers and decrease the price received | Effigy Mounds National MonumentEffigy Mounds National Monument is a national monument in Iowa in the midwestern United States.
