  • Modulation : Q Factor

    What is Q Factor? Q factor (also known as Quality Factor or Q-factor) is defined as a dimensionless parameter that describes the underdamped condition of an oscillator or resonator. The quality factor measures the performance of a coil, a capacitor, or an inductor in terms of its losses and resonator bandwidth. The definition of Quality…

  • Network Topology

    What is a Network Topology? A network topology is defined as the layout or arrangement of elements (usually nodes or links) in a communication network. Network topologies are used to define or describe the arrangement of various types of telecommunication networks – such as computer networks, command and control radio networks, and industrial field busses.…

  • Active Low Pass Filter

    What is an Active Filter? An active filter is a type of filter that includes one or more active circuit components such as a transistor or an operational amplifier (Op-Amp). They derive their energy from an external source of energy and use it to increase or amplify the signal output. Operational amplifiers can also be…
