      Fixed Satellite Service

      Fixed Satellite Service (FSS) is a type of mobile telephone service that allows users in a specific area to make and receive cell phone calls. FSS systems or cell phone towers are placed in strategic, fixed locations and provide service to thousands of individual users simultaneously. Generally, FSS systems provide reception for several square miles

    • What is a MOSFET?

      What is a MOSFET?

      A MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is a device that switches or amplifies an electronic signal. MOSFET technology has made computers much smaller and more efficient than they once were by handling large amounts of electricity in very small spaces. MOSFETs are also crucial for both digital and analog signals and are found

      How GPS Tracking Works

      GPS – A Short Introduction GPS, which stands for Global Positioning System, is a satellite navigation system that can ascertain the latitude and longitude of a GPS receiver device on the Earth.  The GPS consists of more than two dozen global positioning satellites orbiting the earth. Each satellite transmits radio signals, which can help determine

      How to Use a Digital Multimeter

      Anyone planning to work on electronics or automobiles that have been manufactured in the past decade, need to be able to use a digital multimeter. Modern multimeters contain three measuring devices in one: an ammeter, voltmeter, and ohmmeter. The top section of the device contains the digital read out and it can be viewed in

    • Inductor


      An inductor is a conducting coil, wrapped around a core, that creates inductance when an alternating current flows through it. Inductors are used to impede the flow of current in a circuit. The conductor is usually thin magnet wire, and the core is usually air or steel. Working of an Inductor When the alternating current

    • Capacitive Reactance

      Capacitive Reactance

      Capacitive reactance is a term used to describe an effect in capacitors that causes the capacitor’s resistance to change depending on changes in the electric field passing through it. Capacitive reactance is similar to resistance in that it can allow or block varying amounts of voltage in a circuit, but is different because it is

    • BJT Transistors

      BJT Transistors

      Basic diodes are constructed from two semiconductor materials, germanium or silicon, to create a basic PN-junction. When two single diodes are connected to each other back-to-back, two PN-junctions that are connected in series are created. They share a common N or P terminal, which forms the basis of a BJT or Bipolar Junction Transistor. The

    • MURS (Multi Use Radio Service)

      MURS (Multi Use Radio Service)

      MURS, or the Multi-Use Radio Service, is a public radio service created by the FCC in the Fall of 2000 that can be accessed by any individual for personal or business-related purpose. MURS was created for the general public to use without acquiring a license to broadcast, but requires that users remain within the frequencies

    • What is EMI Shielding?

      What is EMI Shielding?

      Electromagnetic Interference (EMI) most commonly occurs in the 104 to 1012 Hertz frequency range of the electromagnetic spectrum. A number of sources create this interference, including radio transmitters, electric motors, power lines, fluorescent lights, and computer circuits. If electrical equipment do not have suitable EMI shielding in place, device failure may result from the interference

    • Multimeter


      A multimeter combines several electrical meters into one hand-held unit. Basic multimeter models measure voltage, current, and resistance. Advanced models also measure temperature, inductance, capacitance, duty cycle, and frequency. They can also test diodes and transistors. Some even work as an oscilloscope. The two main types of multimeters are digital and analogue. Parts of a
