Electrical Symbols — VHF UHF SHF
Ultra high frequency (UHF) is the ITU designation for radio frequencies in the range between 300 MHz and 3 GHz, also known as the decimetre band as the wavelengths range from one meter to one decimetre. Radio waves with frequencies above the UHF band fall into the SHF (super-high frequency) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications.26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.
Electrical Symbols — Electron Tubes
Invented in 1904 by John Ambrose Fleming, vacuum tubes were a basic component for electronics throughout the first half of the twentieth century, which saw the diffusion of radio, television, radar, sound reinforcement, sound recording and reproduction, large telephone networks, analog and digital computers, and industrial process control. From the mid-1950s solid-state devices such as transistors gradually replaced tubes. However, there are still a few applications for which tubes are preferred to semiconductors; for example, the magnetron used in microwave ovens, and certain high-frequency amplifiers.26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.
Digital Communications Network. Computer and Network Examples
The digital communication is a physical transfer of the data over a point-to-point or point-to-multipoint communication channel. Channels can be copper wires, optical fibres, wireless communication channels, etc. The data are realized as electromagnetic signals (radiowave, microwave, electrical voltage, etc.).This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Digital Communication Network diagram.

Electrical Symbols — Qualifying
A qualifying symbol is graphics or text added to the basic outline of a device’s logic symbol to describe the physical or logical characteristics of the device.26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.
Telecommunication networks. Computer and Network Examples
A Telecommunications network is a network of nodes, links, trunks and telephone switches that are connected, operated by telephone companies and realize telephone, audio, visual and data communications among the users. The telecommunications network can also include Internet, microwave, wireless equipment.This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Telecommunications network.
