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. It can also be used to visualize and observe special signals in the vertical blanking interval of a video signal, as well as the colorburst between each line of video.
Robert Hartwig explains the waveform monitor as "providing a graphic display of the black-and-white portion of the picture." [9] The black-and-white portion of the video signal is called the "luminance" due to its fluorescent complexion. The waveform monitor's display of black vs. white levels allows the engineer to troubleshoot the quality of ...
Most modern waveform monitors include vectorscope functionality built in; and many allow the two modes to be displayed side-by-side. The combined device is typically referred to as a waveform monitor, and standalone vectorscopes are rapidly becoming obsolete. [citation needed]
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.
A waveform view allows an IC designer to see the signal transitions over time and the relation of those signals with other signals in an IC design, which is typically written in a hardware description language. Simulators can be used to interactively capture wave data for immediate viewing on a waveform viewer; however, for integrated circuit ...
With an FFT based spectrum analyzer, the frequency resolution is = /, the inverse of the time T over which the waveform is measured and Fourier transformed. With Fourier transform analysis in a digital spectrum analyzer, it is necessary to sample the input signal with a sampling frequency ν s {\displaystyle \nu _{s}} that is at least twice the ...
Rendition of SD ECR-1-1978 color bars Colors are only approximate due to different transfers and color spaces used on web pages and video (BT.601 or BT.709). SMPTE color bars are a television test pattern used where the NTSC video standard is utilized, including countries in North America.
The first step of computing an eye pattern is normally to obtain the waveform being analyzed in a quantized form. This may be done by measuring an actual electrical system with an oscilloscope of sufficient bandwidth, or by creating synthetic data with a circuit simulator in order to evaluate the signal integrity of a proposed design.
