Can This be Possible?

The text in your images is illegible.

As I read it, the upper figure says:

Master >.............................> Master

Slave > ....... AMPLIFIER...... > Slave

Slave > ...............................> Slave

The lower figure says:

Can this be possible?
- The transmission of audio signals is through a wireless means.

- Alien signals will be ignored.

- The setting is a class room.

How does this work?

- The master is used by professors while slaves are for students.

- Anyone who talks will be heard by everyone.

- A multi link type of communication

Please link me the articles or tutorials

So there is an amplifier with a series of audio inputs and outputs. There is a master or primary input/output controller and a series of secondary inputs/outputs. The signals are sent/received wirelessly.

The OP wants to know if this is possible, and if so, he'd like some info or links.

Strictly speaking this cannot be done as it is diagrammed. There are no input microphones that pick up any audio information. There is also no audio network communication paths in any direction, just a single amplifier box.

Now if this was a lecture hall where the Public Address (PA) did the broadcasting of audio and the lecturer could control which microphone was active then a simple relay or FET N:1 multiplexer would work well. A little nuanced ancillary circuitry would be needed to prevent positive feedback into the microphones and status lights on each microphone to indicate who had the PA would be good. However, determining which audience member wanted to and should speak next would be a little tricky.

Doing this wirelessly would require an understanding of allowed RF and/or IR networking protocols. If one had the money and/or security clearance I suspect that one could just purchase such a system. It probably already exists for military patrols using spread spectrum communication.

I cannot read your images. The first graphical image of an array of headphones being the input source to an amplifier that drives another array of headphones makes absolutely no sense to me. Headphones are output devices not input devices. Your second graphical image of a text file should be considered an embarrassment. It is so easy to cut and past text from your document into the CR4 editor.

As for your year end project, this project is supposed to be proof for your professors that you understand instead of just regurgitated the material you were taught. If you do not know if a project approach is even possible then it isn't for you.

John, try uploading your images to a file hosting site like Imgur, Flickr, Google, etc. You can then share the link directly or post the image here from that link following the steps below:

As a student, learning to do your own research will pay handsome dividends when you get your first job.

Yes it is certainly possible, however we cannot provide you with research because this is a homework assignment and the whole point of the final year project is for the student to research the concept themselves not getting others to help. Heck, in my opinion the project and performing your own research and learning along the way is the best part!

Yes students may only have vague ideas or have been given only a few paragraphs of a concept and left to come up with something themselves but that is what Engineering in the real world is all about, and the final year project simulates that.

Be thankful, my final year project accurately simulated real Engineering life when I was given the task of commercialising a product for actual mass production. The product was designed and built as a previous years student project, so badly in fact I had to redesign and rebuild it before even starting my project (two pages just listing everything wrong, broken and missing). Fixing others mistakes and not getting any credit, welcome to the real world.

Perform some research yourself into the application and come back and ask us specific questions.

sorry for the incompleteness... I wnt to her your ideas and opinion.

Yeah it can be done. It is being done with many gaming systems. Your diagram is still not what I'd want to see for an engineering block diagram document but it would be fine for a non-technical presentation document.

Good Luck
