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.
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 wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine function. In mechanics , as a linear motion over time, this is simple harmonic motion ; as rotation , it corresponds to uniform circular motion .
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.
Lissajous curves can also be generated using an oscilloscope (as illustrated). An octopus circuit can be used to demonstrate the waveform images on an oscilloscope. Two phase-shifted sinusoid inputs are applied to the oscilloscope in X-Y mode and the phase relationship between the signals is presented as a Lissajous figure.
Communication with the general public: informs the general public, for example illustrated instructions found in the manuals for automobiles and consumer electronics. This type of technical illustration contains simple terminology and symbols that can be understood by the lay person and is sometimes called creative technical illustration/graphics.
Example of an original vector drawing in Adobe Illustrator.Note the precise edges of shapes and even width of lines that are typical of a drawing program. There are two main types of tools used for digital illustration: bitmapped (also known as "raster") and vector applications.
English: This shows several waveforms: sine wave, square wave, triangle wave, and rising sawtooth wave. The fundamental frequencies of each waveform have the same frequency and phase, for comparison. Uses the data files and the gnuplot code in #Source code below.
