Destructive Interference

  1. Destructive interference leads to only a momentary condition in which the medium's displacement is less than the displacement of the largest-amplitude wave. (Web site)
  2. In a ripple tank, this constructive and destructive interference can be easily controlled and observed. (Web site)
  3. Destructive interference has the tendency to decrease the resulting amount of displacement of the medium. (Web site)

Wave

  1. Wave interference is the phenomenon which occurs when two waves meet while traveling along the same medium. (Web site)
  2. The waves undergo interference and create the pattern represented in the diagram at the right. (Web site)
  3. The two interfering waves do not need to have equal amplitudes in opposite directions for destructive interference to occur. (Web site)
  4. Yet waves meet, produce a net resulting shape of the medium, and then continue on doing what they were doing before the interference. (Web site)
  5. The principles were subsequently applied to the interference of sound waves in Unit 11 of The Physics Classroom. (Web site)

Light

  1. In 1801, Thomas Young successfully showed that light does produce a two-point source interference pattern. (Web site)
  2. Before we investigate the evidence in detail, let's discuss what one might observe if light were to undergo two-point source interference. (Web site)
  3. In astronomy, we will be dealing with the interference of two light waves. (Web site)

Adjacent

  1. The changeover switch 23 is operated by the select signal sel output by the adjacent interference detector 17.
  2. As is shown in FIG. 1, the FM receiver further comprises an adjacent interference detector 17 and a timer 18.
  3. As is known in the art, adjacent waves often causes interference in FM receivers, especially in vehicle-mounted FM receivers.
  4. The adjacent interference detector 17 generates a select signal sel when it detects an adjacent interfering wave in the output of the FM demodulator 16.

Constructive

  1. This can result in either constructive or destructive interference, amplifying or attenuating the signal power seen at the receiver. (Web site)
  2. Constructive interference is observed when a crest meets a crest; but it is also observed when a trough meets a trough as shown in the diagram below. (Web site)
  3. Bright bands are the result of constructive interference while the dark bands are the result of destructive interference.
  4. Constructive interference is observed at any location where the two interfering waves are displaced upward.

Band

  1. Spread and narrow band signals can occupy the same band, with little or no interference. (Web site)
  2. The narrow band is also more prone to interference than the spread-spectrum of CDMA. (Web site)

Adjacent Interference

  1. In addition, it can effectively remove the noise resulting from the adjacent interference.
  2. Secondly, the output of the timer 18 is supplied to the adjacent interference detector 17 as in the second embodiment (FIG. 3).

Correlation

  1. More commonly, however, only the largest correlation peak is used, and all of the other multipath energy represents wideband interference.
  2. Canceling the signals removes the interference due to correlation with other spreading codes.

Same Medium

  1. These questions involving the meeting of two or more waves along the same medium pertain to the topic of wave interference. (Web site)
  2. To begin our exploration of wave interference, consider two pulses of the same amplitude traveling in different directions along the same medium. (Web site)

Interference Occurs

  1. Categorize each labeled position as being a position where either constructive or destructive interference occurs. (Web site)
  2. For instance, when a sine crest with an amplitude of +1 unit meets a sine trough with an amplitude of -1 unit, destructive interference occurs. (Web site)
  3. When constructive interference occurs, a loud sound is heard; this corresponds to a peak on the beat pattern (drawn in green). (Web site)

Frequency Band

  1. And, of course, the higher bands have more bandwidth available for high-speed data, and less probability of interference.
  2. Interference with adjacent channels is limited by the use of band pass filters which only pass signal energy within the specified frequency band. (Web site)
  3. By monitoring the outdoor frequency bands for a period of time, the channels or frequencies which have the least interference power will become apparent. (Web site)
  4. This reduces interference and can increase the number of simultaneous users on one radio frequency band.

Bpl

  1. This article in the Potomac News documents interference to and from the BPL system in Manassas.
  2. Ham radio operators have complained of interference from pilot projects, and are lobbying heavily against BPL deployments.

Fcc

  1. FCC rules require suppression of the signal outside the band to prevent interference. (Web site)
  2. The two sides are miles apart on the interference issue, which the FCC is examining in a request for public comments that has been ongoing since last April. (Web site)

Electromagnetic Interference

  1. EMI An abbreviation for electromagnetic interference. (Web site)
  2. Noise-Like is a distortion or unwanted signal that usually is electromagnetic interference or ambient noise.

Intersymbol Interference

  1. Intersymbol interference attributable to the statistical nature of quantum mechanisms sets the fundamental limit to receiver sensitivity.
  2. It may employ adaptive equalization or other methods to reduce intersymbol interference to levels which are acceptable for discriminating the received point.
  3. This time delay spread of digital signals causes intersymbol interference (ISI), limiting the signaling rate for a desired level of error rate performance. (Web site)
  4. In telecommunication, intersymbol interference ( ISI) is a form of distortion of a signal in which one symbol interferes with subsequent symbols. (Web site)

Reduced Interference

Balanced

  1. Balanced audio is a method of minimising unwanted noise from interference in audio cables.
  2. The idea is that any interference picked up in a balanced cable is eliminated at the point where the cable plugs into a sound mixer or other equipment. (Web site)

Co-Channel Interference

  1. Two transmitters cannot broadcast on the same frequency in the same area as this would cause co-channel interference.
