  5. Waves

  6. Sine Waves and Square Waves

  7. Sine Waves and Square Waves

  8. Exponents and Logarithms

  9. Decibels

  10. Viewing Signals in Time and Frequency

  11. Viewing Signals in Time and Frequency

  12. Analog and Digital Signals in Time and Frequency

  13. Fouries Synthesis

  14. Noise in Time and Frequency Ampere's Law states that any electrical current is surrounded by a magnetic field.

  15. Sources of Noise Nearby cables that carry data signals EMI [electromagnetic interference] Interference by electromagnetic signals that can cause reduced data integrity and increased error rates on transmission channels. RFI [radio frequency interference] The radio frequencies that create noise that interferes with information being transmitted across unshielded copper cabling. Laser noise at the transmitter or receiver of an optical signal

  16. White Noise Noise that affects all transmission frequencies equally is called white noise

  17. NarrowBand Noise Noise that only affects small ranges of frequencies is called narrowband interference.

  18. Bandwidth Analog bandwidth typically refers to the frequency range of an analog electronic system. [Hz] Digital bandwidth measures how much information can flow from one place to another in a given amount of time. [bps - bit per second]

  35. New Standard • On June 20, 2002, the Category 6 (or Cat 6) addition to the TIA-568 standard was published. • This new standard specifies the original set of performance parameters that need to be tested for Ethernet cabling as well as the passing scores for each of these tests. • A quality cable tester is the Fluke DSP-LIA013 Channel/Traffic Adapter for Cat5e.
