Signal tracer For long pulse trains, a cyclic redundancy check may be calculated and displayed, giving the tech insight into the content of circuits that are switching rapidly. Signal tracer A signal tracer is a piece of electronic test equipment used to troubleshoot radio and other electronic circuitry. Usually a very simple device, it normally provides an amplifier, and a loudspeaker, often battery-powered and packaged into a small, hand-held test probe. An optional diode detector is usually also provided, allowing the detection of amplitude-modulated signals. The technician injects a test signal into the device under test. Then, by using the signal tracer,
Strength of a graph Strength of a graph In the branch of mathematics called graph theory, the strength of an undirected graph corresponds to the minimum ratio "edges removed"/"components created" in a decomposition of the graph in question. It is a method to compute partitions of the set of vertices and detect zones of high concentration of edges, and is analogous to graph toughness which is defined similarly for vertex removal. The strength formula_1 of an undirected simple graph "G" = ("V", "E") admits the three following definitions: Computing the strength of a graph can be done in polynomial time, and the first such
