What is the difference between Analog signal and Binary signal?
An analog signal has a sine wave form and a binary signal has a block "wave" form. The binary signal is either on or off ("up" or "down"), and never anything in between. analog: http://img99.imageshack.us/img99/7723sineuk6.jpg binary: http://img154.imageshack.us/img154/1894binarypb6.png ...

What is the difference between narrow-band channels and wide-band channels?
In the Narrow-band channel the signal see the channel as a flat channel , and the signal pass the channel without any type of cut . In the other hand the signal that passes through the wide-band channel see the channel as a frequency selective channel and cut values from the signal . I mean that if the bandwidth for the signal is lager than the bandwidth for the channel then, the channel is a wide-band channel, and if the bandwidth for the...
What converts a binary signal to analog?

Difference between the digital and analog signal?
I'm not sure if you are speaking of a specific instance.... However, a digital signal is a binary representation of the analog signal. The analog signal is constantly measured and the amplitude (voltage at the time of sample) of the analog signal is converted to a binary number at specific intervals (the frequency of the sample rate). The higher the frequency of the sample rate, the more accurate the representation of the analog signal. ...

What is a binary digital signal?
A synchronous or asynchronous stream of signal consisting only of zero(no voltage) and one(position voltage) is called binary data stream. They may be bytestream, wordstream and so on. Sending unique binary pulses periodically create a binary digital signal. For example, you want to pass the number 346F5A through binary digital signal it will be 001101000110111101011010 Break it 0011-0100-0110-1111-0101-1010 you will find the binary equivalents of each digit. This example is very simple. Usually complex form of data are sent to and fro through data lines, be...

What is difference between source encoder and channel encoder?
A source encoder converts client input to a binary stream. This is typically done by sampling an analog input, digitizing the samples and coding them into a binary stream. A common component that does all this is called a Codec. A channel encoder converts a binary stream to an analog signal that can be transmitted over distances as tones, radio waves and/or light. The channel encoder can take a number of bits from the bitstream at a time to create a multibit...
How does a remote change a channel?
Pushing a button to change the channel on a remote control begins a process that causes the remote to carry out the command. It works something like this: You want to go to channel 13 and push these buttons on the remote control. This causes it to touch the contact beneath it, and this completes the "channel change" circuit on the integrated circuit board, which detects this. The integrated circuit then sends the "channel change" command to the LED (Light-emitting diode) at the...
