The vector stencils library "Delay elements" contains 12 symbols of delay elements for drawing electrical schematics and electronic circuit diagrams.
"An analog delay line is a network of electrical components connected in series, where each individual element creates a time difference or phase change between its input signal and its output signal. It operates on analog signals whose amplitude varies continuously. An example is a bucket-brigade device. Other types of delay line include acoustic, magnetostrictive, and surface acoustic wave devices. A series of RC networks can be cascaded to form a delay. A long transmission line can also provide a delay element. The delay time of an analog delay line may be only a few nanoseconds or several milliseconds, limited by the practical size of the physical medium used to delay the signal and the propagation speed of impulses in the medium."

The symbols example "Design elements - Delay elements" was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the Electrical Engineering solution from the Engineering area of ConceptDraw Solution Park.

The vector stencils library "TV, Photo and Video" contains 52 television, photography and video icons.
Use it to design your audio, video and multimedia illustrations, presentations, web pages and infographics with ConceptDraw PRO diagramming and vector drawing software.
"Digital video is a representation of moving visual images in the form of encoded digital data. This is in contrast to analog video, which represents moving visual images with analog signals." [Digital video. Wikipedia]
The clipart example "TV, Photo and Video" is included in the Audio, Video, Media solution from the Illustrations area of ConceptDraw Solution Park.
