Waveform shaping in electronics is the modification of the shape of an electronic waveform. It is in close connection with waveform diversity [ 1 ] and waveform design, [ 2 ] which are extensively studied in signal processing .
A sine, square, and sawtooth wave at 440 Hz A composite waveform that is shaped like a teardrop. A waveform generated by a synthesizer. In electronics, acoustics, and related fields, the waveform of a signal is the shape of its graph as a function of time, independent of its time and magnitude scales and of any displacement in time.
The wave vector and angular wave vector are related by a fixed constant of proportionality, 2 π radians per cycle. It is common in several fields of physics to refer to the angular wave vector simply as the wave vector, in contrast to, for example, crystallography. [1] [2] It is also common to use the symbol k for whichever is in use.
Illustration by Jessie Willcox Smith (1863–1935). An illustration is a decoration, interpretation, or visual explanation of a text, concept, or process, [1] designed for integration in print and digitally published media, such as posters, flyers, magazines, books, teaching materials, animations, video games and films.
Adobe Illustrator is a vector graphics editor and design software developed and marketed by Adobe. Originally designed for the Apple Macintosh , development of Adobe Illustrator began in 1985 . Along with Creative Cloud (Adobe's shift to a monthly or annual subscription service delivered over the Internet ), Illustrator CC was released.
Examples of pulse shapes: (a) rectangular pulse, (b) cosine squared (raised cosine) pulse, (c) Dirac pulse, (d) sinc pulse, (e) Gaussian pulse A pulse in signal processing is a rapid, transient change in the amplitude of a signal from a baseline value to a higher or lower value, followed by a rapid return to the baseline value.
Three Phase alternating current waveform. This figure illustrates one voltage cycle of a three-phase system, labeled 0 to 360° (2 π radians) along the time axis. The plotted line represents the variation of instantaneous voltage (or current) with respect to time.
A modulated wave resulting from adding two sine waves of identical amplitude and nearly identical wavelength and frequency. A common situation resulting in an envelope function in both space x and time t is the superposition of two waves of almost the same wavelength and frequency: [2]
