What is characteristics impedance?

The characteristic impedance or surge impedance belongs to a uniform transmission line, usually written Z0. It is the ratio of the amplitudes of a single pair of voltage and current waves propagating along the line in the absence of reflections.


Which is better high input impedance or low input impedance and why?

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.


How to distinguish between characteristic impedance and input impedance?

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.


Input impedance is greater than to load impedance?

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.


Why is output impedance kept low?

To get all the audio 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 at least 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.

What is the physical significance of the impedance?

Impedance may refer to: the ratio of the voltage phasor to the electric current phasor, as in Electrical impedance, a measure of opposition to time-varying electric current in an electric circuit. Characteristic impedance, a measure of opposition to electric current propagation in a transmission line. Impedance matching and Impedance mismatch. Vacuum impedance, a universal constant. Electromagnetic impedance, a constant related to electromagnetic wave propagation in a medium. Mechanical impedance, a measure of opposition to motion of a structure subjected to a force. Acoustic impedance, a constant related to the propagation of sound waves in an acoustic medium. Linear response function, a general way to represent the input-output characteristics of a system. Scroll down to related links and look at an example: "Interconnection of two audio units".

What is the degree of resistivity?

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.

Is characteristics impedance of a filter is same as output or load impedance?

load impedance


What will happen to the input signal when the transmission line is terminated by its characteristic impedence?

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.

no. input impedance is low & output impedance is high
