A simulation framework to analyze signal flows in complex networks. Python Branch: master New pull request. Find File. Download ZIP. Sign in Sign up. Launching GitHub Desktop On this page Signal Flow is discussed. The Schematic diagram layout is very important. You want to clearly illustrate the important information.
Signal Flow Analysis, Used - AbeBooks
You want to minimize wire crosses and create a pretty picture. A schematic should be a picture suitable for framing and provide an intuitive description of circuit operation. In a schematic a lot of the information is displayed in a subtle manner by the layout, i. For Circuit Analysis, we need to show the information needed for analysis.
Terms used in SFG
This includes the component type and electrical value. Other data can be hidden. A simulation schematic contains the information needed to perform a circuit simulation.
It can be used for circuit analysis. If a schematic lacks inputs or attempts to violate a circuit law, the simulator will issues error warnings and refuse to simulate the circuit. A simulation schematic from the schematics page is shown below. The schematic shows the netlist, the input stimuli, and the output load. The circuit components and nodes are labeled. This is sufficient for analysis. For a clear circuit description we need to make the schematic layout reveal the circuit operation. Inputs should be on the left and outputs on the right. The circuit input signal travels from left to right across the schematic.
This is what circuit do. They take input stimuli and propagate the input signals to the output. In a good schematic, the input to output signals paths should be obvious and only flow from left to right across the schematic. The left to right signal flow is arbitrary. The circuit does not know what the schematic looks like and simply does not care.
The circuit will continue to do its thing. We need to mold the circuit operation description into a standard signal flow template. For clarity, inputs must be on the left and outputs on the right. The Left side of a schematic should contain only inputs.
Similarly, the right side should contain only outputs. This is very important.
How do signals propagate from input to output? There are many possible descriptions.
K9 relates signal flow to the schematic. Signals can only flow thru circuit components. The schematic shows what components are present and how they are connected. Signals flow is via circuit paths. In this case there are two direct signal paths from the input to the output. The input signal can go thru R3 to node 1, and thru R1, R2, and R4 to the output. The other path is input thru R3, R5, and R4 to the output. There are many ways to create a SFG.
The traditional approach is to create the SFG from a set of equations. In this case the signal flow may not match your circuit intuition.
Control Systems/Signal Flow Diagrams
Signal flow is thru circuit components and the SFG layout matches the schematic layout. This creates a good signal flow description if the schematic has a good layout. Signal flow is shown via directed branches. The gain labels were selected to match the resistor label. Each resistor creates signal flow in two directions. Components can require two branches. The left to right main signal flow and reverse signal flow denoted by the f feedback in the label. The reverse signal flow for R3 has a gain of zero.
Vin is an ideal voltage source. The circuit can not change the value of this source. To keep things simple, zero gain branches are not shown. The signal paths have gains. The gains are shown on the SFG. Brandy will provide the passive circuit gains and Mason will correct the path gains for circuit interaction. You need to concentrate on the difficult part, making a clear circuit description. The schematic should emphasize the main signal flows. The components that create the main signal path are placed horizontally.
Components that connect to ground are shown with a vertical orientation. They are not part of the main input to output signal path. The orientation can thus be used to make the input to output signal path more obvious. If the schematic is an accurate description of the Signal Paths, the circuit description can be the schematic or the SFG.
