What is a symmetrical network?
Symmetric-network meaning A network in which all devices can send and receive data at the same rates. Symmetric networks support more bandwidth in one direction as compared to the other, and symmetric DSL offers clients the same bandwidth for both downloads and uploads.
What is symmetry and reciprocity?
As nouns the difference between symmetry and reciprocity is that symmetry is exact correspondence on either side of a dividing line, plane, center or axis while reciprocity is the characteristic of being reciprocal, eg of a relationship between people.
What is the reciprocal network?
Reciprocity in electrical networks is a property of a circuit that relates voltages and currents at two points. The reciprocity theorem states that the current at one point in a circuit due to a voltage at a second point is the same as the current at the second point due to the same voltage at the first.
What is a symmetrical two port network?
A symmetrical two-port has the same characteristics at each of the ports. An example of a symmetrical network is a transmission line with a uniform cross section. A reciprocal two-port has a response at Port 2 from an excitation at Port 1 that is the same as the response at Port 1 to the same excitation at Port 2.
How do you know if a network is symmetrical?
Symmetric Network: A symmetric network has a single route for incoming and outgoing network traffic. As such traffic takes the same route when entering or the network.
What are the properties of symmetrical networks?
A network is symmetrical if its input impedance is equal to its output impedance. Most often, but not necessarily, symmetrical networks are also physically symmetrical. Sometimes also antimetrical networks are of interest. These are networks where the input and output impedances are the duals of each other.
What is reciprocal theorem?
(5.22) Thus, in its simplest form, the reciprocal theorem states the following: The deflection at point 1 in a given direction due to a unit load at point 2 in a second direction is equal to the deflection at point 2 in the second direction due to a unit load at point 1 in the first direction.
What are reciprocal devices?
A reciprocal network is one in which the transmission of a signal between any two ports does not depend on the direction of propagation- input and output ports are interchangeable (scattering parameter S21=S12, S13=S31, etc.) A network is known to be reciprocal if it is passive and contains only isotropic materials.
How do you determine the given two port network is symmetrical?
A two-port network is said to be symmetrical if the input and output ports can be interchanged without altering the port voltages and currents. A network is said to be reciprocal if the ratio of the response to the excitation is invariant to an interchange of the positions of the excitation and response of the network.
