how can i get started in learning how wireless transmitter and receiver circuit work

 

It is impossible to know your skill level, as you have neglected to mention it, so here is the beginning: http://www.allaboutcircuits.com/vol_1/index.html

 

im still a beginner

but the link you send to me aint good enough cos i have it already

i need how to start the construction

 

but the link you send to me aint good enough cos i have it already

Does that make it not good? Do you understand everything in there? No? Then keep reading...

 

Then go buy a ready-made solution, it is what you are asking for anyway...

That's actually great advice. Study what The_RB wrote about the cheap RF PCBs that are on e-bay, buy a couple, experiment with them, and then you can be an expert, at least on that particular set of devices.

Most of your posts sound like you want someone to "whisper the secret" of electronics in your ear, but that is impossible. It takes study, experimentation, and time to learn. I, like many others here, am doing exactly that: studying and experimenting. The experts here (and I am not one of them) got to be experts through years and years of effort.

ETA: I just took my own advice, and ordered this.

These are great fun to "project" with.

Is it possible to transmit audio with them?

 

I haven't tried that yet. I use them to send ADC and other on/off stuff.

Depending on how you do it, yes.... but, you may/will need to limit some capabilities...

 

You can encode the audio and send it digitally using delta modulation.

Would the quality be good enough to use for a wireless headset for TV?

 

It simply depends on the clock frequency that one chooses
