  1. Signal reflection

    Unreferenced date March 2007 Signal reflection occurs when a signal is transmitted along a transmission medium, such as a reflections on copper lines copper cable or an optical fiber . Some of the signal power may be reflected back to its origin rather than being carried all the way along the cable to the far end. This happens because imperfections in the cable cause Electrical impedance impedance mismatches and non linear changes in the cable characteristics. These abrupt changes in characteristics cause some of the transmitted signal to be reflected. In radio frequency RF practice, this is often measured in a dimensionless ratio known as voltage standing wave ratio VSWR with a VSWR bridge. The ratio of energy bounced back depends on the Impedance matching impedance mismatch . Mathematically, it is defined using the reflection coefficient . Because the principles are the same, this concept is perhaps easiest to understand when considering an optical fiber. Imperfections in the glass create mirrors that reflect the light back along the fiber. Impedance discontinuities cause attenuation , attenuation distortion , standing waves , ringing signal ringing and other effects because a portion of a transmitted signal will be reflected back to the transmitter transmitting device rather than continuing to the receiver radio receiver , much like an echo. This effect is compounded if multiple discontinuities cause additional portions of the remaining signal to be reflected back to the transmitter. This is a fundamental problem with the daisy chain electrical engineering daisy chain method of connecting electronic components. When a returning reflection strikes another discontinuity, some ... and measuring how long the reflection takes to return. If only reflection magnitudes are desired ...

  1. Reflection theorem

    Confusing article date February 2010 For reflection principles in set theory, see reflection principle . In algebraic number theory , a reflection theorem or Spiegelungssatz German language German for reflection theorem see Spiegel and Satz disambiguation Satz is one of a collection of theorems linking the sizes of different ideal class group s or ray class group s , or the sizes of different isotypic component s of a class group. The original example is due to Ernst Kummer Ernst Eduard Kummer , who showed that the class number of the cyclotomic field math mathbb Q left zeta p right math , with p a prime number, will be divisible by p if the class number of the maximal real subfield math mathbb Q left zeta p right math is. Another example is due to Scholz ref A. Scholz, Uber die Beziehung der Klassenzahlen quadratischer Korper zueinander, J. reine angew. Math. , 166 1932 , 201 203. ref . A simplified version of his theorem states that if 3 divides the class number of a real quadratic field math mathbb Q left sqrt d right math , then 3 also divides the class number of the imaginary quadratic field math mathbb Q left sqrt 3d right math . Both of the above results are generalized by Leopoldt s Spiegelungssatz , which relates the p rank s of different isotypic components of the class group of a number field K , considered as a Galois module module over the Galois group of a Galois extension K k . Extensions of his Spiegelungssatz were given by Oriat and Oriat Satge, where class groups were no longer associated with characters of the Galois group of K k , but rather by ideals in a group ring over the Galois group of K k . Leopoldt s Spiegelungssatz was generalized in a different direction by Kuroda, who extended it to a statement about ray class group s.
