Transmission line max power transfer
I'm studying transmission lines and came up with the question why (voltage) reflection coefficient being zero is not equal to maximum power transfer (conjugate matching). I did some search and found ...

Calculating for impedance matching of more complex circuits
When I start off to calculate the impedance from Z-input, how can I reach to antenna's Z-output which may be variable, for example 50 ohm.
I have several good links on Internet:

Maximum power transfer and minimization of wave reflection: Understanding the difference on intuitive level
It is well known that there are two usual methods in impedance matching: if we have a network consisting of a source with impedance \$Z_S\$ and load with impedance \$Z_L\$ then we have two options to ...

Why is output power such a meaningful quantity in speakers?
Loudspeakers, for example, should be impedance matched to deliver the highest power from the source to the speakers. But why do we care about power so much? A speaker is at its simplest, a coil around ...

Impedance Matching between Source and Load
I am having this basic doubt
In the basic crude basic block diagram, we have a source, transmission line and load, all having an impedance of 50Ohms. But according to maximum power transfer theorem, ...

Confusion between the necessity of maximum voltage and maximum power transfer
This is a conceptual question therefore I want to ask with an example.
I'm wondering in which cases impedance matching is used.
For example, if one has a sensor which can be modeled as voltage ...

Amplifier and Speaker matching while in Bridged Mono Mode
I’m a little confused as to how I should be matching my amplifier and speaker in bridged mono mode. Let’s say I have the following,
• Amplifier Power: 100W at 8 ohms
• Amplifier Supported Output ...

On a transmission line, why does max power transfer occur at impedance matching?
I do not intuitively understand why max power is transferred when the characteristic impedance of a transmission line is equivalent to the impedance of a load.
A voltage wave going through the ...

impedance matching and impedance briging
Why in RF receiver we need impedance matching for maximum power transfer but not maximum voltage? And why there is no Impedance matching or Power matching in audio engineering?
Is it depends on the ...
