The knowledge of the 3000 most frequent English word families or the 5000 most frequent words provides 95% vocabulary coverage of spoken discourse. [21] For minimal reading comprehension a threshold of 3,000 word families (5,000 lexical items) was suggested [ 22 ] [ 23 ] and for reading for pleasure 5,000 word families (8,000 lexical items) are ...
These two forms of vocabulary are usually equal up until grade 3. Because written language is much more diverse than spoken language, print vocabulary begins to expand beyond oral vocabulary.

For example, a signal (10101010) has 50% duty cycle, because the pulse remains high for 1/2 of the period or low for 1/2 of the period. Similarly, for pulse (10001000) the duty cycle will be 25% because the pulse remains high only for 1/4 of the period and remains low for 3/4 of the period. Electrical motors typically use less than a 100% duty ...
Plot of normalized function (i.e. ()) with its spectral frequency components.. The unitary Fourier transforms of the rectangular function are [2] = = (), using ordinary frequency f, where is the normalized form [10] of the sinc function and = (/) / = (/), using angular frequency , where is the unnormalized form of the sinc function.
Use of creaky voice across general speech and in singing is termed "vocal fry". Some evidence exists of vocal fry becoming more common in the speech of young female speakers of American English in the early 21st century, [8] with researcher Ikuko Patricia Yuasa finding that college-age Americans perceived female creaky voice as "hesitant, nonaggressive, and informal but also educated, urban ...

In healthy people, the filling level of the jugular vein should be less than 4 centimetres vertical height above the sternal angle. [2]
