      Symbol Rate

      The symbol rate is the rate of state changes on a communications circuit. If a circuit can carry two tones per second, the circuit has a symbol rate of two. Circuits then use different modulation techniques to carry multiple bits per symbol. If the circuit is limited to two different tones, the first tone can

    • UHF (Ultra High Frequency)

      UHF (Ultra High Frequency)

      UHF is an acronym for a band of radio frequencies often used to broadcast television signals. Mobile phones and satellite radio also use UHF signals. The letters ‘UHF’ stand for: Ultra High Frequency. UHF Frequencies Any radio frequency between 300 MegaHertz (MHz) and 3,000 MHz (or 3 GigaHertz) is considered to be in the UHF

    • Galvanic Isolator

      Galvanic Isolator

      A galvanic isolator is any device that connects two circuits together without allowing electricity to flow directly from one circuit to the other. Instead of transferring electricity through direct contact, galvanic isolators use other means, such as electromagnetism, mechanical devices, optical systems, or acoustic systems to convert the electricity into another form of energy, transfer

    • Retrograde Orbit

      Retrograde Orbit

      A retrograde orbit is an orbit where the satellite travels in an East to West direction instead of the common West to East orbit. The normal West to East orbits are known as prograde orbits. Retrograde orbits are uncommon due to the much higher velocities necessary for successful launch and the associated higher costs. During
