    Linear Algebra: Used to solve systems of linear equations that arise in circuit analysis. Applications include network theory and the analysis of electrical circuits using matrices and vector spaces; Calculus: Essential for understanding changes in electronic signals. Used in the analysis of dynamic systems and control systems.

    Simulation-based methods for time-based network analysis solve a circuit that is posed as an initial value problem (IVP). That is, the values of the components with memories (for example, the voltages on capacitors and currents through inductors) are given at an initial point of time t 0 , and the analysis is done for the time t 0 ≤ t ≤ t f ...

  6. Ground loop (electricity) - Wikipedia

    en.wikipedia.org/wiki/Ground_loop_(electricity)

    In this situation the video cable is grounded at the projector end to the home electrical system, and at the other end to the cable TV's ground, inducing a current through the cable which distorts the picture. The problem is best solved with an isolation transformer in the CATV RF feed, a feature included in some CATV box designs.

  7. Bridge circuit - Wikipedia

    en.wikipedia.org/wiki/Bridge_circuit

    A bridge circuit is a topology of electrical circuitry in which two circuit branches (usually in parallel with each other) are "bridged" by a third branch connected between the first two branches at some intermediate point along them. The bridge was originally developed for laboratory measurement purposes and one of the intermediate bridging ...

    Here’s another problem that’s very easy to write, but hard to solve. All you need to recall is the definition of rational numbers. Rational numbers can be written in the form p/q, where p and ...

  9. USB communications - Wikipedia

    en.wikipedia.org/wiki/USB_communications

    To solve this problem, the device keeps track of the type of DATAx packet it last accepted. If it receives another DATAx packet of the same type, it is acknowledged but ignored as a duplicate. Only a DATAx packet of the opposite type is actually received. If the data is corrupted while transmitted or received, the CRC check fails.
