Despite the similarity in pronunciation, these words bear little semantic resemblance to one another. phase /feɪz/ n. These systems are desirable when we want to minimize the distortion on the shape of a signal. In other words x is phase φ , i. [countable] a stage in a process of change or development: Her temper tantrums are just part of the phase she's going through. Systems with constant group delay are referred to as linear phase systems. PHASE meaning: 1 : a part or step in a process one part in a series of related events or actions; 2 : a short period of time during which a person behaves in a particular way or likes a particular thing A phase is a particular stage in a process or in the gradual development of something. Generally, the PLL is designed to have a stable lock point with a π/2 phase offset - π/2 is a metastable lock point because it is in a positive feedback operation range In Lissajous figures, the relative phase between the harmonic signals plays an important role in determining the pattern, and the instantaneous point on the figure defines the instantaneous relative phase of the two signals. Phase can of course be a function of time, i. See examples of phase used in a sentence. PHASE definition: any of the major appearances or aspects in which a thing of varying modes or conditions manifests itself to the eye or mind. any distinct or characteristic period or stage in a sequence of events or chain of development: there were two phases to the resolution; his immaturity was a passing phase. Figure 1: The chemical potential of a solid liquid and gas. . , phased, phas•ing. Phase definition: A distinct stage of development. In physics, phase space is a concept which unifies classical (Hamiltonian) mechanics and quantum mechanics; in mathematics, phase space is a concept which unifies symplectic geometry with harmonic analysis and PDE. Illustrated in Wikipedia's article Lunar phase. Phase and faze are homophones (words pronounced alike but different in meaning, derivation, or spelling) that may easily be confused. , cos φ ( t) . The lowest chemical potential is the equilibrium phase. Meaning, pronunciation, picture, example sentences, grammar, usage notes, synonyms and more. In physics, phase space is a concept which unifies classical (Hamiltonian) mechanics and quantum mechanics; in mathematics, phase space is a concept which unifies symplectic geometry with harmonic analysis and PDE. , v. In a second-order phase transition the first derivatives of G vanish and the Clapeyron equation is replaced by a condition involving second derivatives. For example: cos ( ω t + φ ) 0 0 In other words, the signal phase φ ( t) is φ ( t ) = ω 0 t + φ Second order transitions. cosx. , cos φ and sin φ. A phase is one of the forms in which matter can exist, such as solid, liquid, or a gas. Astronomy the particular, usually repeated appearance presented by the moon or a planet at a given time: What phase is the moon in? v. n. Feb 19, 2026 · (astronomy) A particular appearance or state in a regularly recurring cycle of changes with respect to quantity of illumination or form, or the absence, of a body's illuminated disk.
