Absolute phase refers to the phase of a waveform relative to some standard (strictly speaking, phase is always relative).
The amplitude of a periodic variable is a measure of its change over a single period (such as time or spatial period).
In physics, two wave sources are perfectly coherent if they have a constant phase difference and the same frequency, and the same waveform.
A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle, defined so that a full rotation is 360 degrees.
A displacement is a vector whose length is the shortest distance from the initial to the final position of a point P. It quantifies both the distance and direction of an imaginary motion along a straight line from the initial position to the final position of the point.
Frequency is the number of occurrences of a repeating event per unit of time.
A harmonic is any member of the harmonic series, a divergent infinite series.
In electrical engineering, a sinusoid with angle modulation can be decomposed into, or synthesized from, two amplitude-modulated sinusoids that are offset in phase by one-quarter cycle (/2 radians).
Indiana University (IU) is a multi-campus public university system in the state of Indiana, United States.
Instantaneous phase and instantaneous frequency are important concepts in signal processing that occur in the context of the representation and analysis of time-varying functions.
In mathematics, a Lissajous curve, also known as Lissajous figure or Bowditch curve, is the graph of a system of parametric equations which describe complex harmonic motion.
The National Institute of Standards and Technology (NIST) is one of the oldest physical science laboratories in the United States.
In mathematics, the origin of a Euclidean space is a special point, usually denoted by the letter O, used as a fixed point of reference for the geometry of the surrounding space.
An oscilloscope, previously called an oscillograph, and informally known as a scope or o-scope, CRO (for cathode-ray oscilloscope), or DSO (for the more modern digital storage oscilloscope), is a type of electronic test instrument that allows observation of varying signal voltages, usually as a two-dimensional plot of one or more signals as a function of time.
In the context of phasors, phase angle refers to the angular component of the complex number representation of the function.
In physics, the phase problem is the problem of loss of information concerning the phase that can occur when making a physical measurement.
The phase velocity of a wave is the rate at which the phase of the wave propagates in space.
In physics and engineering, a phasor (a portmanteau of phase vector), is a complex number representing a sinusoidal function whose amplitude (A), angular frequency (ω), and initial phase (θ) are time-invariant.
In the physics of wave propagation, a plane wave (also spelled planewave) is a wave whose wavefronts (surfaces of constant phase) are infinite parallel planes.
Polarization (also polarisation) is a property applying to transverse waves that specifies the geometrical orientation of the oscillations.
In complex analysis, the principal values of a multivalued function are the values along one chosen branch of that function, so that it is single-valued.
The radian (SI symbol rad) is the SI unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics.
In mechanics and physics, simple harmonic motion is a special type of periodic motion or oscillation motion where the restoring force is directly proportional to the displacement and acts in the direction opposite to that of displacement.
A sine wave or sinusoid is a mathematical curve that describes a smooth periodic oscillation.
A spectrogram is a visual representation of the spectrum of frequencies of sound or other signal as they vary with time.
A turn is a unit of plane angle measurement equal to 2pi radians, 360 degrees or 400 gradians.
In physics, a wave is a disturbance that transfers energy through matter or space, with little or no associated mass transport.
In physics, interference is a phenomenon in which two waves superpose to form a resultant wave of greater, lower, or the same amplitude.
A waveform is the shape and form of a signal such as a wave moving in a physical medium or an abstract representation.
