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.

What is the need of impedance matching?
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".
How a transformer can be used as impedance matching?
If the line impedance is Z0 and the load is ZL then connect the load using a transformer with N turns ration. N=sqrt(Z0/ZL)
What is passive amplification?
Impedance matching network perform the passive amplification.
In a multistage amplifier input impedance is high and output impedance is low justify the statement?
no. input impedance is low & output impedance is high
How a characteristic impedance of 50ohm is matched with load impedance of 150ohms?
This is done using an impedance matching network (or filter), which is composed of multiple capacitors and inductors. Since these networks are made of capacitors and inductors, the matching networks are specific to a given frequency.If you need to create one, I recommend referencing a book on electronic networks. There is usually a section on filters and passive filter designs that may give a step by step approach to developing one.Also, you can create a filter using active components, such as operation amplifiers. The Op amps should be chosen with care to insure the desired frequency is attainable. This may be a simpler approach than developing a passive filter, depending on your requirements.
What is meant by matching?
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.

Why emitter follower preferred to transforms as a impedance matching?
because it has high input impedance and low output impedance
What is impedance coupled amplifier?
The purpose of impedance matching is to provide for the highest efficiency between either the stages of an amplifier circuit or from a device to the amplifier for the same purpose. Impedance matching us used to make the circuits compatible based on electrical characteristics of a particular circuit from one section (or stage) to the next.
Can an impedance matching device reduce electrical costs?
An impedance matching device is used to test the resistance, inductive reactant and capacitive reactant in a circuit. If one component did not match the impedance of the conductor, some of the current will be lost by the conductors itself. In conclusion if electricity is lost, the component needs to meet its regular voltage. It consumes more voltage than expected because of the loss. Impedance matching device can actually reduce electrical cost.
What is the advantages of buffer circuits in digital electronics?
buffer circuits helpful in overcoming the impedance matching problem.for example if we want to send a signal from one devise to other ,if there is no impedance matching between this two then signal is not transfered.now if we use buffer in between these two devises then the buffer without changing the signal shape or value it simply transffers the signal
What are the importance of impedance matching in amplifiers?
Two reasons. 1...When impedance of source and destination match, power transfer is maximum. 2...If a long transmission line is involved, the characteristic impedance of the line must match the destination impedance, or reflections will occur on the line.
How a transformer can be used as impedance matching?
If the line impedance is Z0 and the load is ZL then connect the load using a transformer with N turns ration. N=sqrt(Z0/ZL)
Application of a common - collector amplifier circuit?
Common collector amplifier can be used as a voltage buffer and in impedance matching
What is passive amplification?
Impedance matching network perform the passive amplification.
What does impedance in ham radio mean?
Impedance is not unique to ham radio and applies to all electronics. Impedance is a property of electrical circuits that can impede the current from flowing.
What improves sound transmission from the transducer element into tissue?
impedance matching layer
