The reason you are puzzled is because television video signals are AM modulated and television audio signals are FM modulated. So you have to carry out two different demodulation processes to obtain both the video and the audio. Hope this sheds some light on your question.
You have to understand that with Ohm's law as V = IR
You can also use it as I = V/R and R = V/I
So for any part of your circuit, if you have two known values, you can find the other.
Don't know about your particular battery but here is a link to a datasheet that I looked at. It clearly shows "1.2Ah @ 900 ohms to 5.4V @ 23°C".

I would first be absolutely certain that I have the two cables wired together properly. In my experience these wall worts have poor regulation so if you measure 5v with an open circuit, you should expect it to drop when connected. How much it drops depends on your load, the phone. Maybe your...
The DC current gain in your circuit is only 11.9. That's your Ic / Ib. From the **broken link removed**, with Collector current of 10mA, you should have a minimum currrent gain of 80. Your circuit doesn't seem to have that. If this was an actual constructed circuit, it would seem there is...
These gates can be combined pretty much any way you need to. You first need to know what your inputs are and what kind of output do you want. The inputs could be sensors detecting such things as water level, temperature, amount of light, and many other things. Then your output would be what...
To what language and cultural issues were you referring?
Yes of course Nasrinta needs help, but it is not helpful of you to point out that they do not neet to say "I need help". I look at that as a cultural issue.
What teaching and learning did you have in mind?
As you pointed out, there are...
We don't all come from the same cultural backgrounds and we don't all speak (write) English as a first language. Let's get past the language and cultural issues and get on to the teaching and learning process.
Yes, Kemiyun, of course the bandwidth can be reduced by filtering. I think fran1942 was asking about AM Modulation without any consideration given to modifying his signals.
Your bandwidth is determined by the highest frequency that you use. In your case it is 3.3KHz. So your bandwidth would be 2 times your highest frequency. 2 * 3.3KHz = 6.6KHz
