Frequency domain¶
In mathematics, physics, electronics, control systems engineering, and statistics, the frequency domain refers to the analysis of mathematical functions or signals with respect to frequency (and possibly phase), rather than time, as in time series.
Core Idea¶
Frequency domain is treated here as the recurring computerscienceandinformation identity summarized by this source-grounded definition: In mathematics, physics, electronics, control systems engineering, and statistics, the frequency domain refers to the analysis of mathematical functions or signals with respect to frequency (and possibly phase), rather than time, as in time series. converts the function's time-domain representation, shown in red, to the function's frequency-domain representation, shown in blue. In mathematics, physics, electronics, control systems engineering, and statistics, the frequency domain refers to the analysis of mathematical functions or signals with respect to frequency (and possibly phase), rather.
Scope of Application¶
-
Types. Although "the" frequency domain is spoken of in the singular, there are a number of different mathematical transforms which are used to analyze time-domain functions and are referred to as "frequency.
-
Magnitude and phase. In using the Laplace, Z-, or Fourier transforms, a signal is described by a complex function of frequency: the component of the signal at any given frequency is given by a.
-
Magnitude and phase. The response of a system, as a function of frequency, can also be described by a complex function.
-
Types. These are the most common transforms, and the fields in which they are used.
-
Discrete frequency domain. For example, the discrete Fourier transform maps a function having a discrete time domain into one having a discrete frequency domain.
Clarity¶
A clear use of Frequency domain names the carrier, the operative relation, and the conditions under which the source treats the identity as present. The minimal definition is In mathematics, physics, electronics, control systems engineering, and statistics, the frequency domain refers to the analysis of mathematical functions or signals with respect to frequency (and possibly phase), rather than time, as in time series.
Manages Complexity¶
Frequency domain compresses multiple computerscienceandinformation details into a stable diagnostic relation. The source shows both the central mechanism—for example, using the Fourier transform, a sound wave, such as human speech, can be broken down into its component tones of different frequencies, each represented by a sine wave of a different amplitude and phase.—and the practical consequence—a complex valued frequency-domain representation consists of both the magnitude and the.
Abstract Reasoning¶
- Type the carrier. Identify the computerscienceandinformation entities to which the claim applies.
- State the relation. Use the source-grounded identity: In mathematics, physics, electronics, control systems engineering, and statistics, the frequency domain refers to the analysis of mathematical functions or signals with respect to frequency (and possibly phase), rather than time, as in time series.
- Check operation and conditions. The response of a system, as a function of frequency, can also be described by a complex function.
- Demand recognition evidence.
Knowledge Transfer¶
Within the home domain. Knowledge about Frequency domain transfers literally when a new case preserves the same carrier type, relation, and recognition test. Although "the" frequency domain is spoken of in the singular, there are a number of different mathematical transforms which are used to analyze time-domain functions and are referred to as "frequency domain" methods. In using the Laplace, Z-, or Fourier transforms, a signal is described by a complex function of frequency: the component of the signal at any given frequency is given by.
Neighborhood in Abstraction Space¶
Frequency domain sits in a moderately populated region (57th percentile for distinctiveness): it has near-neighbors but no dense thicket of look-alikes.
