Some words, phrases and structures are used much more than others in any language. When you learn these most common forms first, you greatly increase your communicative ability in French in a minimum of time. Speaking High Frequency French an exceptionally complete, fast and easy to understand audiocassette course and book to mastering the reading, writing, and speaking of practical everyday 'high frequency' French. This tapes and text quickly take the learner from beginning to advanced level French by teaching the listener to speak a maximum amount of useful and practical high frequency French in a minimum of time. Research shows that most foreign language learners spend over half of their time looking up meanings and guessing at answers instead of learning the language. Speaking High Frequency French is an exciting and effective 'learn on your own' taped course that literally 'takes the foreign out of language by providing clear English translations, explanations, and answers for all French exercises.

Maximum usable frequency - Maximum usable frequency (MUF) describes, in radio transmission, using reflection from the regular ionized layers of the ionosphere, the upper frequency limit that can be used for transmission between two points at a specified time. This index is especially useful in regard to shortwave transmissions.

Lowest usable high frequency - The lowest usable high frequency (LUF), in radio transmission, is that frequency in the HF band at which the received field intensity is sufficient to provide the required signal-to-noise ratio for a specified time period, e.g.

Continuous phase-frequency-shift keying - Continuous phase-frequency-shift keying (CPFSK) is a commonly-used variation of frequency-shift keying (FSK), which is itself a special case of analog frequency modulation. FSK is a method of modulating digital data onto a sinusoidal carrier wave, encoding the information present in the data to variations in the carrier's instantaneous frequency between one of two frequencies (referred to as the space frequency and mark frequency).

Eight-to-Fourteen Modulation - ... EFM) is an encoding technique used by CDs and MiniDiscs. EFM belongs to the class of DC-free Run Length Limited (RLL) codes because it ensures that a) the spectrum (power density function) of the encoded sequence vanishes at the low-frequency end and b) both the minimum and maximum number of consective bits of the same kind are within specified bounds.

'Frequency Modulation' - 'Frequency Modulation' WINDSHIELD MOUNTED RAIN SENSOR WINDSHIELD MOUNTED RAIN SENSOR Senses rain on windshield 'frequency modulation' and turns wipers on Automatically turns wipers on to the appropriate speed Manual override function Highly-versatile device for automatic wiping of vehicle windscreen when it is wet due to moisture, raindrops or even mud. It works by reflecting harmonious light beams within a windscreen. When raindrops fall onto windscreen, this harmony is disturbed, creating a drop in the light beam intensity. The system then activates the wipers to operate in fully automatic mode. The amount of raindrops (measured in milliliters) will automatically determine how fast 'frequency modulation' and frequent the wiper will operate (depending on your vehicle's wiper settings). Most vehicle wipers operate in 3 different modes: Intermittent (low speed 'frequency modulation' and low frequency), slow (low speed 'frequency modulation' and medium frequency) 'frequency ...
