If one or more peaks in an 800-line spectrum exceeds the average plus sigma amplitude criterion, that fact alone does not indicate a significant problem (see the section on diagnostic strategies). Figure 3. The relative acceptance criteria was generated specifically for the 1,250 ...

  • Low noise block downconverter ( LNB )

    It is the device on the front of a satellite dish that receives the very low level microwave signal from the satellite, amplifies it, changes the signals to a lower frequency band and sends them down the cable to the indoor receiver. The expression low noise refers the the quality of the first stage input amplifier transistor. The quality is measured in units called Noise Temperature, Noise ...Proper Lubrication Keeps Bearings Rolling AlongAs the elements roll over the clumps and particles the generate high frequency sound emissions, which are measured in three different frequency bands (high, medium and low) and categorized into five grades or levels.1 The number of vibration peaks above certain reference levels determines the grease noise classification.
