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.

Most of the electrical symbols can be changed in their appearance, styles and colors according to users' requirements. Electrical symbols are used to represent various electrical and electronic devices in a schematic diagram of an electrical or electronic circuit.

The following table lists some VHF UHF SHF electrical symbols in our electrical diagram software.

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation".

How to Create an Electrical Diagram Using VHF UHF SHF Library

  • Open ConceptDraw DIAGRAM new document page.
  • Select libraries from Electrical Engineering section.

    Libraries from Electrical Engineering section

  • There are a few different ways to place an object into your drawing:

    • Click on an object and then click on the document, at the place you want the object to be inserted.
    • Perform a drag-and-drop from the library to your document.
    • Double click on an object’s icon in the library to place an object in the center of your document.
  • Select the Smart Connector tool Smart Connector. To connect elements using this tool, drag the connector from one connect dot to another.You can use Layers to place connections on different layers.
  • Result: Electrical Diagram.

Types of Flowcharts →

A flowchart is a simple but very functional tool when it comes to understanding a workflow or to removing unnecessary stages from a process. When drawing flowcharts, keep in mind that there are four common types of flowcharts, like document flowcharts and data flowcharts that show control over a data or document flow over a system. To show controls on a physical level, use system flowcharts. In addition, to show controls in a program, you can draw a program flowchart. This flowchart diagram represents the piece of an article editing process, that involves the author and editor. It was created using the Basic Flowchart notation that consists from the basic flowchart symbols. The start and the end of the process are indicated with "Terminator" symbols. The "Process" symbols show the action steps consisting from making edits and searching for a compromise, when the author does not agree with the suggestions of the editor. The "Process" symbol is the general symbol in process flowcharts. The "Decision" symbol indicates a branching in the process flow. There are two branches indicated by a Decision shape in the current flowchart (Yes/No, Disagree/Agree). This basic flowchart can be used as a repeating unit in the workflow diagram describing the working process of some editorial office.Types of Flowcharts *

Process Flowchart →

When trying to figure out the nature of the problems occurring within a project, there are many ways to develop such understanding. One of the most common ways to document processes for further improvement is to draw a process flowchart, which depicts the activities of the process arranged in sequential order — this is business process management. ConceptDraw DIAGRAM is business process mapping software with impressive range of productivity features for business process management and classic project management. This business process management software is helpful for many purposes from different payment processes, or manufacturing processes to chemical processes. Business process mapping flowcharts helps clarify the actual workflow of different people engaged in the same process. This samples were made with ConceptDraw DIAGRAM — business process mapping software for flowcharting and used as classic visio alternative because its briefly named "visio for mac" and for windows, this sort of software named the business process management tools. This flowchart diagram shows a process flow of project management. The diagram that is presented here depicts the project life cycle that is basic for the most of project management methods. Breaking a project into phases allows to track it in the proper manner. Through separation on phases, the total workflow of a project is divided into some foreseeable components, thus making it easier to follow the project status. A project life cycle commonly includes: initiation, definition, design, development and implementation phases. Distinguished method to show parallel and interdependent processes, as well as project life cycle relationships. A flowchart diagram is often used as visual guide to project. For instance, it used by marketing project management software for visualizing stages of marketing activities or as project management workflow tools. Created with ConceptDraw DIAGRAM — business process mapping software which is flowcharting visio alternative or shortly its visio for mac, this sort of software platform often named the business process management tools.Process Flowchart

Swim Lane Diagrams →

Job duties in small companies are usually spread randomly among workers, causing lots of problems and misunderstanding. One of the ways to restore order in business processing is to create a cross-functional flowchart with swim lanes that would represent every step in production system. Another advantage of using swim lanes flowchart is that it represents not only processes, but people responsible for them. Swim lane diagram is a kind of a process flow diagram. Its special feature is that it joins the features of process flow diagrams with organizational charts. Thus, a swim lane diagram display a participant of the business process in a conjunction with general flow of the business system. A swim lane diagram is looks similar to a swimming pool's lanes. Lanes can be horizontal and vertical. The lanes are pointed out relatively to resource name, which is assigned on implementation of the given part of the business process. ConceptDraw Business Process Mapping solution delivers the ability to design develop swim lanes flowcharts using the vector graphic objects of Swim Lanes library.Swim Lane Diagrams *
