What else can I help you with?
Why emitter follower preferred to transforms as a impedance matching?
because it has high input impedance and low output impedance
How you can eliminate loading effect in amplifiers?
By increasing the input impedance of amplifier.
What are typical values of input impedance and outoput impedance of ce amplifiers?
Output of the power amplifier is smaller 0.1 ohms and input of the loudspeaker is more than 4 ohms.
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.
Is a voltage source a zero or infinite impedance?
Obviously it's not infinite impedance--that would mean it soaks up all the voltage. It can't be zero impedance either...that would be a superconductor, and there aren't many of those around. Voltage sources have impedance, but it's not infinite. Sometimes the impedance of the source is critical--radio frequency amplifiers have to be impedance matched to their transmitting antennas if you don't want to burn them out.
Why do amplifiers have zero output impedance?
Good amplifiers have low output impedances. The reason is "impedance bridging". Scroll down to related links and look at "Calculation the damping of impedance bridging or power matching an interface connecting Zout and Zin".
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".
Why is impedance matching used in electronics?
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.
Why emitter follower preferred to transforms as a impedance matching?
because it has high input impedance and low output impedance
What are the most used instrument amplifiers?
The most used instrument amplifiers are also some of the most popular amplifiers namely Marshall, Crate and Fox amplifiers. The impedance of these amplifiers does not need to match making it perfect for instrument use.
Will a 4 ohm sub work on a 8 ohm system?
With system you mean the output impedance of an amplifier. No Problem to do this, but there are really no amplifiers with an output impedance of 8 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
How do you connect 4 ohm speaker to 16 output amplifier?
No Problem to do this, but there are really no amplifiers with an output impedance of 16 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
Can 8 ohm subs be used on 4 ohm amps?
No Problem to do this, but there are really no amplifiers with an output impedance of 4 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
How do you parallel 2 speaker 8 ohm on 8 ohm amply?
No Problem to do this, but there are really no amplifiers with an output impedance of 8 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".

What is the recommended impedance matching between an 8 ohm amp and a 16 ohm speaker for optimal performance?
The recommended impedance matching between an 8 ohm amp and a 16 ohm speaker for optimal performance is to use a speaker with an impedance that is equal to or higher than the amp's impedance.
What happens if you connect one 8 ohm speaker to an amp rated 350w at 4 ohm?
No Problem to do this, but there are really no amplifiers with an output impedance of 4 ohms on the market. All loudspeaker amplifiers have an impedance of less than 0.5 ohm. Scroll down to related links and look at "Impedance bridging - Wikipedia".
