How to change digital signals to analog signals and again from analog to digital signals?
modem Measuring usually the voltage of the analog signal many times a second in binary number code generates a digital signal, and using a binary number code to control the voltage of an output results in a reproduced analog signal. That is what is done for stuff like digital television. A Modem (prior answer) is for when the analog signals are used to connect digital computers (like yours) together, usually over a long distance.
Is PCM is an example of analog to digital?
No, Pulse Code Modulation is a communication method used to carry digital data but is not part of any analog to digital conversion. PCM is often used to carry audio data as a digital stream and therefore is the encoding used as the signal is first converted to a digital format.
How are digital signals in radio broadcast converted to analog signals inside digital transmission equipment before sending the signals to the antenna for transmission?
The digital signals is not converted BACK to analog! it is transmitted in digital form and the receiver is converting it back to analog to drive the speakers. The signal from the microphone is converted from analog to digital with an A/D converter chip, digital signals consist of pulses of different lengths that is switching the transmitter on and off in about the same way as the old Morse code transmissions but at a much higher rate (millions of times higher)
What does digital data mean?
A digital signal is a physical signal that is a representation of a sequence of discrete values (a quantified discrete-time signal), for example of an arbitrary bit stream, or of a digitized (sampled and analog-to-digital converted) analog signal. The term digital signal can refer to either of the following:any continuous-time waveform signal used in digital communication, representing a bit stream or other sequence of discrete valuesa pulse train signal that switches between a discrete number of voltage levels or levels of light intensity, also known as a line coded signal or baseband transmission, for example a signal found in digital electronics or in serial communications, or a pulse code modulation (PCM) representation of a digitized analog signal.A signal that is generated by means of a digital modulation method (digital passband transmission), to be transferred between modems, is in the first case considered as a digital signal, and in the second case as converted to an analog signal.
Why digital signal is better than analog signal?
the digital code is binar. so if you get a signal it is absolut. analogue signals can be interfered or altered through interferation.
Is Morse code digital?
Yes
What is the second step in the pulse code modulation process?
digital converter extracts samples of analog signal from input siganl digital converter quantizes analog sample and assignes a binary numbervalue to it digital coanverter encodes a quantized analog signal to transmit it across a digital network
What are the advantages of digital over analog?
The advantage of analog over digital or vice versa , is dependent on the input information type and / or signal amplitude where applicable , also on what the application is and other considerations like information / signal processing , storage , etc. The choice is decided by the advantages as per the requirements. As a rule the information carried by an analog signal is dependent on its instantaneous magnitude or position.Thus it is highly susecptible to corruption by extraneous noise sources which can affect the magnitude arbitrarily. On the other hand a digital signal typically carries information as changes in amplitude level between two ( or more ) arbitrarily predefined levels, arranged in a predetermined format and grouping ( more familiar as a code ). As long as the digital signal can be retrived without major loss in blocks of code , the original information can be mathematically retrived. Whenever the information and / or signal level is very small and / or in analog form , invariably some form of analog processing is required before any meaningful conversion to digital format or processing can be done. Now due to vast processing powers of digital circuits & computers , the advantage of analog is limited to very specialised requirements where the disadvantages of digital format would outweigh any other considertions. So for all purposes it would be invariably advantageous to use digital format and convert to analog whenever required. The only notable analog format which will always be required is for human sound & visual interface ( or for that matter other senses ) which the body perceives and processes only as analog signals , even the pseudo analog modes of Class D Audio Amplifiers , LCD Displays , Projection , Digital Printing etc. which operate in the Digital mode to simulate analog signal output. It may be noted that the Morse Code was essentially a digital format, while Semaphore ( uses Flag & Hand positions to convey information ) was an analog signal by virtue of hand position.

Why do mobile phones need the anologue-to-digital and digital-to-analog chip?
All digital devices that produce audio out put IE CD player / dab radio have a digital to analog converter chip, all sounds you hear are analogue if it were in digital all you would hear is just high pitch screeching no matter what sound you are listening to, it would be like hearing Morse code speeded up thousand fold constantly, phones transmit a digitally signal, there for when you speak into it it has to convert your analogue voice into digital to transmit then convert it back to analogue so you can under stand.
What are the advantages of an analog signal?
Though we, as people, can interpret digital signals (if we train ourselves to do it - like Morse code), we do better with analog signals. Music and speech as well as most other sound is analog. We interpret analog audio signals almost instantly, and without even thinking about it. Without analog signals, most of our listening activities are for nothing. Let's take sound to the electronics forum. Electronically, a digital signal requires that we convert our analog signal to a digital one in an audio-to-digital converter (AtoD). And we have to convert it back at the other end. We can do all this, but it takes extra stages and effort to make it happen. Certainly it's the only way we can move all the signals we need to move, like with cell phone traffic. Without digital techniques, we'd be dead in the water trying to serve all the cellular customers we serve, but voice traffic starts and ends as analog signals 'cause we human critters can relate to them better.
What do you mean by analog signal and digital signal?
Digital signals have discrete encoded states that they switch between. They can only assume the defined encoded values. Errors can often be easily detected and sometimes corrected.Analog signals are continuous and change smoothly from one value to another, passing through all intermediate values. There is no way to identify errors.
