Basic Notions

Fig. 3.10. Common-Drain Circuit

3.2.3. Common-Gate Circuit

Figure 3.11 shows a common-gate circuit that consists of the MOSFET, the drain resistance R_d, the supply voltage source V_b, the signal voltage source V_i, and the gate series resistance R _GV the latter has no effect on the transfer characteristic but influences the frequency response and the bandwidth.

Vowels –belong to the class of speech sounds in the production of which there is no obstruction to the airflow as it passes from the larynx to the lips.

Consonants – the sounds made by a closure or narrowing in the vocal tract.

Idiolectal variation embraces the individual peculiarities of articulating sounds, caused by the shape and form of the speaker’s speech organs and by his articulatory habits.

Diaphonic variation is caused by definite historical tendencies active in certain localities. Diaphonic variants do not affect intelligibility of speech, yet they inform the listener about the speaker’s origin and his social standing.

Allophonic variation is conditioned by phonetic position and phonetic environment.

Assimilation refers to a modification in the articulation of a consonant under the influence of a neighbouring consonant.

Articulation basis is a set of articulatory habits characteristic of all the native speakers of a language.

Transcription – a visual system of notation of the sound structure of speech, the representation of speech sounds by means of a special set of phonetic symbols indicating an approximate specification of the articulations involved.

Phonological or broad transcription – the type that uses a simple set of symbols, not meant to designate phonetic details of pronunciation.

Allophonic or narrow transcription – the type that uses special symbols (diacritics) to show more phonetic details.
