Download PDF by Joachim Franz: EMV. Störungssicherer Aufbau elektronischer Schaltungen

Dieses Buch stellt erstmalig eine Methodik für die examine und die Lösung der EMV-Problematik vor. Sie basiert auf einer eingehenden Betrachtung der Koppelmechanismen und auf der vom Verfasser entwickelten "Stromanalyse". Damit kann die Entwicklung elektronischer Produkte preiswerter, deutlich schneller und mit wesentlich besseren EMV-Eigenschaften realisiert werden.

Example text

He had noted that in existing computers the use of majority logic - ‘what I tell you three times is true’ - coupled with a search procedure for finding new elements, resulted in reliability of computation. It was with this background in mind that Von Neumann attacked these problems. His principal solution t o this problem was obtained in the following manner. The reliable recognition of input configurations is required of some finite automaton, that corresponds say, t o the reliable computation of a Boolian function (cf McCulloch and Pitts, 1943, op.

G. the symbio-organism (9, - 1 1 , 1, - 7) and ( 5 , - 1 I , 1, - 3) can crossbreed t o give (5, - 11, 1, - 7) and (9, - 11, 1 , - 3) as well as the parent symbio-organisms. (c) Great variability - each symbio-organism may consist of many elements (genes) and each element may have several states (alleles). The number of varieties which can arise is practically unlimited. (d) Parasitism - same symbio-organisms cannot reproduce completely, a n d degenerate into simpler symbio-organisms (cf Von Neumann), unless they can interact with other symbio-organisms.

Which will themselves be aggregates of elementary parts’. In all the automata considered, a location will exist where such instructions I can be inserted so that when such automata are being described, the specification for the location is understood to form part of the description. Thus the statement ‘inserting a given instruction I into a given automaton A’ is meaningful. (b) A copying automaton, B Since T is an aggregate of elementary parts, the copying automaton has merely to duplicate any particular aggregate, much as a tape reading machine can reproduce :iny input tape.
