Boken har ett lättförståeligt och pedagogiskt språk och är rikt illustrerad.Denna andra upplaga innehåller inga förändringar av innehållet ­jämfört med den första upplagan.Ur innehållet: • Logisk algebra och binär aritmetik• Grindar och vippor• Kretsteknologier – klassiska och moderna• Kombinatoriska kretsar och sekvenskretsar• Minnen – klassiska och moderna• Digital konstruktion – mikroprocessorer, PLD, ASIC, FPGA• Anpassning till en analog omvärld – A/D- och D/A-omvandling, indikatorer• Introduktion till VHDL-språket. Denna bok är framförallt avsedd för ingenjörsutbildning på högskolenivå, men lämpar sig även väl för företagsutbildningar och självstudier.

The field of particle physics is developing very rapidly. During this past year, physicists added a new instrument to their arsenal for the study of quark-quark, quark-lepton, and lepton­ lepton interactions. This machine, the PROTON-ANTIPROTON COLLIDER, achieved the highest energy in the world. With its five detectors, it is beginning to explore hitherto inaccessible regions for new physics (Section I). Lepton-Iepto~ machines with detectors at full efficiency are producing copious data of the very highest precision. The possibility of glueballs and the detailing of the properties of the upsilon family have been of major importance this year (Section II). The particle jets which are believed to be direct manifesta­ tions of the quark structure of matter continue to provide valuable data against which we can test the ideas of QCD (Section III). With the advent of more and better data it is now possible to study in detail the formation evolution of hadronic states. Especially interesting are the properties of heavy quark states (Section IV). A far-seeing look into the future development of any fecund scienti­ fic field is rarely accurate, but is always stimulating (Section V). It is against this background of participating in the clarifi­ cation of the Physics in Collision that we continue this series.

It is generally felt in the cosmology and particle astrophysics community that we have just entered an era which later can only be looked back upon as a golden age. Thanks to the rapid technical development, with powerful new telescopes and other detectors taken into operation at an impressive rate, and the accompanying advancement of theoretical ideas, the picture of the past, present and future Universe is getting ever clearer. Some of the most exciting new findings and expected future developments are discussed in this invaluable volume.The topics covered include the physics of the early Universe and ultra-high energy processes. Emphasis is also put on neutrino physics and astrophysics, with the evidence for non-zero neutrino masses emerging from both solar neutrinos and atmospheric neutrinos covered in great depth. Another field with interesting new results concerns the basic cosmological parameters, where both traditional methods and the potential of new ones, like deep supernova surveys and acoustic peak detections in the cosmic microwave background, are thoroughly discussed. Various aspects of the dark matter problem, such as gravitational lensing estimates of galaxy masses, cluster evolution and hot cluster electron distortions of the thermal microwave background spectrum, are also discussed, as are particle physics candidates of dark matter and methods to detect them. Cosmic rays of matter and antimatter are included as a topic, and so is the problem of the enigmatic dark energy of the vacuum.
