Amplitude
The amplitude of a periodic variable is a measure of its change over a single period (such as time or spatial period).

Arbitrary waveform generator
An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms.

Basis function
In mathematics, a basis function is an element of a particular basis for a function space.
New!!: Waveform and Basis function · See more »
Crest factor
Crest factor is a parameter of a waveform, such as alternating current or sound, showing the ratio of peak values to the effective value.
New!!: Waveform and Crest factor · See more »
DC bias
When describing a periodic function in the time domain, the DC bias, DC component, DC offset, or DC coefficient is the mean amplitude of the waveform.

Decibel
The decibel (symbol: dB) is a unit of measurement used to express the ratio of one value of a physical property to another on a logarithmic scale.

Display device
A display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people).
New!!: Waveform and Display device · See more »
Fourier series
In mathematics, a Fourier series is a way to represent a function as the sum of simple sine waves.
New!!: Waveform and Fourier series · See more »
Fourier transform
The Fourier transform (FT) decomposes a function of time (a signal) into the frequencies that make it up, in a way similar to how a musical chord can be expressed as the frequencies (or pitches) of its constituent notes.

Frequency
Frequency is the number of occurrences of a repeating event per unit of time.
New!!: Waveform and Frequency · See more »
Frequency domain
In electronics, control systems engineering, and statistics, the frequency domain refers to the analysis of mathematical functions or signals with respect to frequency, rather than time.
New!!: Waveform and Frequency domain · See more »
Harmonic
A harmonic is any member of the harmonic series, a divergent infinite series.
New!!: Waveform and Harmonic · See more »
Observation
Observation is the active acquisition of information from a primary source.
New!!: Waveform and Observation · See more »
Oscilloscope
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.

Sawtooth wave
The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform.
New!!: Waveform and Sawtooth wave · See more »
Signal
A signal as referred to in communication systems, signal processing, and electrical engineering is a function that "conveys information about the behavior or attributes of some phenomenon".
New!!: Waveform and Signal · See more »
Sine wave
A sine wave or sinusoid is a mathematical curve that describes a smooth periodic oscillation.
New!!: Waveform and Sine wave · See more »
Spectrum analyzer
A spectrum analyzer measures the magnitude of an input signal versus frequency within the full frequency range of the instrument.
New!!: Waveform and Spectrum analyzer · See more »
Square wave
A square wave is a non-sinusoidal periodic waveform in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum.
New!!: Waveform and Square wave · See more »
Subtractive synthesis
Subtractive synthesis is a method of sound synthesis in which partials of an audio signal (often one rich in harmonics) are attenuated by a filter to alter the timbre of the sound.
New!!: Waveform and Subtractive synthesis · See more »
Time
Time is the indefinite continued progress of existence and events that occur in apparently irreversible succession from the past through the present to the future.
New!!: Waveform and Time · See more »
Triangle wave
A triangle wave is a non-sinusoidal waveform named for its triangular shape.
New!!: Waveform and Triangle wave · See more »
Trigonometry
Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships involving lengths and angles of triangles.
New!!: Waveform and Trigonometry · See more »
Wave
In physics, a wave is a disturbance that transfers energy through matter or space, with little or no associated mass transport.
New!!: Waveform and Wave · See more »
Wave packet
In physics, a wave packet (or wave train) is a short "burst" or "envelope" of localized wave action that travels as a unit.
New!!: Waveform and Wave packet · See more »
Waveform monitor
A waveform monitor is a special type of oscilloscope used in television production applications.
New!!: Waveform and Waveform monitor · See more »
Waveform viewer
A waveform viewer is a software tool for viewing the signal levels of either a digital or analog circuit design.
New!!: Waveform and Waveform viewer · See more »
