The level of a video signal usually corresponds to the brightness, or luminance, of the part of the image being drawn onto a regular video screen at the same point in time. A waveform monitor can be used to display the overall brightness of a television picture, or it can zoom in to show one or two individual lines of the video signal.
A digital pattern generator is a piece of electronic test equipment or software used to generate digital electronic stimuli. Digital electronics stimuli are a specific kind of electrical waveform varying between two conventional voltages that correspond to two logic states ("low state" and "high state", "0" and "1").
Video processing – for interpreting moving pictures; Wireless communication – waveform generations, demodulation, filtering, equalization; Control systems; Array processing – for processing signals from arrays of sensors; Process control – a variety of signals are used, including the industry standard 4-20 mA current loop; Seismology
The electrocardiograph is a medical device to record the waveform of the electric signals that are associated with the beating of the heart; that waveform has important diagnostic value. Waveform generators, that can output a periodic voltage or current with one of several waveforms, are a common tool in electronics laboratories and workshops.
Examples of such oscilloscope-based instruments include waveform monitors for analyzing video levels in television productions and medical devices such as vital function monitors and electrocardiogram and electroencephalogram instruments. In automobile repair, an ignition analyzer is used to show the spark waveforms for each cylinder.

For example, wobulation of advanced radar waveform modulations – where the repetition rate or center frequency of a signal is changed in a repetitive fashion to reduce the probability of interception. In large-screen television technology, wobulation is Hewlett-Packard's term for a form of interlacing designed for use with fixed pixel ...
For example, signals that can assume three possible states are called three-valued logic. In a digital signal, the physical quantity representing the information may be a variable electric current or voltage, the intensity, phase or polarization of an optical or other electromagnetic field , acoustic pressure, the magnetization of a magnetic ...
