3Frequency of optimum transmission — Frequency of optimum transmission, in the transmission of radio waves via ionospheric reflection, is the highest effective (i.e. working) frequency that is predicted to be usable for a specified path and time for 90% of the days of the month. It… …
4Frequency management challenges in military forces — Every military force has a goal to ensure and have permanent access in the spectrum of radio frequencies to meet its vital military tasks. This is based on strategies, doctrines and different policies that military forces adhere to.The nature of… …
5Frequency-hopping spread spectrum — (FHSS) is a method of transmitting radio signals by rapidly switching a carrier among many frequency channels, using a pseudorandom sequence known to both transmitter and receiver. A spread spectrum transmission offers three main advantages over… …
6Effective Resolution Bandwidth — Effective Resolution BandwidthThe frequency band of a signal converter where ENOB is still guaranteed.It is limited by dynamic quantization problems …
7Frequency synthesizer — A frequency synthesizer is an electronic system for generating any of a range of frequencies from a single fixed timebase or oscillator. They are found in many modern devices, including radio receivers, mobile telephones, radiotelephones, walkie… …
8Effective mass — In solid state physics, a particle s effective mass is the mass it seems to carry in the semiclassical model of transport in a crystal. It can be shown that, under most conditions, electrons and holes in a crystal respond to electric and magnetic …
9Effective population size — In population genetics, the concept of effective population size N e was introduced by the American geneticist Sewall Wright, who wrote two landmark papers on it (Wright 1931, 1938). He defined it as the number of breeding individuals in an… …
10Effective interest rate — The effective interest rate, effective annual interest rate, Annual Equivalent Rate (AER) or simply effective rate is the interest rate on a loan or financial product restated from the nominal interest rate as an interest rate with annual… …
