reflected impedence is a tool to analyse resonant coupling..
no. input impedance is low & output impedance is high
Impedance matching is setting the input impedance (load) equal to the fixed output impedance (source) to which it is connected, in order to maximize the power transfer.Matching is obtained when Zload = Zsource.In audio and sound engineering we have really no impedance matching. There is only impedance bridging. Zload >> Zsource.Scroll down to related links and look at "Impedance bridging - Wikipedia".
Transformer Z-ratio = (Zpri / Zsec) = (Vpri / Vsec)2 It could also be the damping factor DF = Zload / Zsource The damping factor DF is the load impedance Zload (input impedance) divided by the the source impedance Zsource (output impedance).
This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.This is similar to "equivalent resistance", but impedance is a more accurate concept in the case of AC.The equivalent resistance (or equivalent impedance) means that if you replace all the resistances under consideration with one equivalent resistance, the result on the circuit will be the same.
Impedance matching is used in electronics to get an electronic device with an input and output source to work. Impedance matching will give the electronic it's maximum transfer of voltage. An example of this are FM radio receivers.
To get all the voltage from a source to a target without loss you need voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
The characteristic impedance of a transmission line is the ratio of voltage to current of the propagating electrical wave. The line input impedance is the result of the superposition of forward and reverse, or reflected waves when the terminating impedance is not adapted. If the line is infinite, nothing returns from its end and only the forward wave exits. The voltage to current ratio is then the line characteristic impedance. Remark that the same occurs when the line is terminated by its characteristic impedance, the forward wave finds a perfect continuity to the load and no energy is reflected back to the line. A matched line is like an infinite line when looked from the input terminals. Long real lossy lines also act as infinite lines for the energy of the reflected wave is dissipated along the line before reaching the source.
When waves encounter a boundary where there is a change in impedance (such as air to water), some of the wave energy is reflected back. The amount of reflection depends on the difference in impedance between the two mediums. This reflection phenomenon is the reason why we can hear echoes in an empty room or see our reflection in a mirror.
You may be mixing up 'impedance' with 'apparent power'.Impedance is the vector sum of an a.c. load's resistance and reactance, and is expressed in ohms. Apparent power is the vector sum of true power and reactive power, and is expressed in volt amperes.Apparent power is also the product of the square of the load current and the impedance of the load.
Impedance matching is the electronics design practice of setting the input impedance of an electrical load equal to the fixed output impedance of the signal source to which it is connected. That is done usually in order to maximize the power transfer and to minimize all reflections from the load. Zinput = Zoutput.
Reflected power in a klystron refers to the power that is sent back towards the input of the klystron due to impedance mismatches or other factors. This can cause inefficiencies in the klystron operation as the reflected power is not contributing to the desired output. Proper tuning and matching of the klystron components can help minimize reflected power.
That depends on the output impedance. In electronic we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance. An input impedance is called also a load impedance or an external impedance. An output impedance is called also a source impedance or an internal impedance.
When the input signal to a transmission line is terminated by its characteristic impedance then the signal gets absorbed in the terminating impedance itself and is not reflected back along the line. Thus, no standing waves are produced in the transmission line.

Acoustic impedance is the measurement that indicates how much sound pressure the vibration of molecules at a given frequency is generated. Attenuation refers to the gradual loss in intensity through a medium, such as light and sound in water.
Assuming electrical resistivity is meant, the Ohm is the simple measure.For AC quantities, impedance, still measured in Ohms is the unit, but with a phase angle included.add. The concept of impedance has been applied very usefully to Electrical transmission.Acoustic waves at least have two components (velocity and pressure), but the only application of impedance in that area seems to be in the measurement of sound absorption [in the impedance tube method].The concept of impedance should be able to be applied to thermal transfer as well, but my knowledge is deficient.
The characteristic impedance or surge impedance belongs to uniform transmission lines.In electronic gears we use voltage bridging, that is a relative low output impedance to a higher input impedance. Usualy the input impedance is more than ten times higher then the output impedance.An input impedance is called also a load impedance or an external impedance.An output impedance is called also a source impedance or an internal impedance.
