Signal flow graph of a circuit containing a two port. The forward path from input to output is shown in a different color. The dotted line rectangle encloses the portion of the SFG that constitutes the two-port. The figure to the right depicts a circuit that contains a y-parameter two-port network. V in is the input of the circuit and V 2 is ...
List of free analog and digital electronic circuit simulators, available for Windows, macOS, Linux, and comparing against UC Berkeley SPICE. The following table is split into two groups based on whether it has a graphical visual interface or not.
A modern line card has no two-to-four wire conversion whatsoever; it is strictly an analog/digital interface to a system that has a completely digital and integrated signal path internally. Using actual wires to circuit switch a telephone call became obsolete when the crossbar switch (a mechanical system) was replaced by 4ESS electronic ...
The load line, usually a straight line, represents the response of the linear part of the circuit, connected to the nonlinear device in question. The points where the characteristic curve and the load line intersect are the possible operating point (s) ( Q points ) of the circuit; at these points the current and voltage parameters of both parts ...
A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations.
Made in Japan, this was also the first calculator to use an LED display, the first hand-held calculator to use a single integrated circuit (then proclaimed as a "calculator on a chip"), the Mostek MK6010, and the first electronic calculator to run off replaceable batteries. Using four AA-size cells the LE-120A measures 4.9 by 2.8 by 0.9 inches ...
The TI-Nspire Lab Cradle is a Calculator-Based Laboratory system introduced in 1994. It is a portable data collection device for the life sciences. The CBL system was replaced in 1999 by the CBL 2. The TI-Nspire Lab Cradle has three analog and two digital inputs with a sampling rate of up to 100,000 readings per second.
As a word bond graph, this system would look like: A half-arrow is used to provide a sign convention, so if the engine is doing work when τ and ω are positive, then the diagram would be drawn: This system can also be represented in a more general method. This involves changing from using the words, to symbols representing the same items.
