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.
The Software Communications Architecture (SCA) is an open architecture framework that defines a standard way for radios to instantiate, configure, and manage waveform applications running on their platform. The SCA separates waveform software from the underlying hardware platform, facilitating waveform software portability and re-use to avoid ...
The video signal and carrier wave both exist in waveform and when the carrier wave "carries" the video signal, the shape of carrier wave is changed and the changed carrier wave is the RF signal. Hence, how the shape of carrier wave is changed is the key to classify the types of video modulation.
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.
The impression of information on a carrier wave for transmission. monolithic microwave integrated circuit An integrated circuit that operates in microwave frequencies and that can be fabricated by printed circuit board technology. monoscope A raster scan video device that generates a single fixed image for test or identification purposes. Moore ...
Signal processing is an electrical engineering subfield that focuses on analyzing, modifying and synthesizing signals, such as sound, images, potential fields, seismic signals, altimetry processing, and scientific measurements. [1]
A waveform viewer is a software tool for viewing the signal levels of either a digital or analog circuit design. [1] Waveform viewers comes in two varieties: simulation waveform viewers for displaying signal levels of simulated design models, and
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.
