What is flow of communication process?
The flow of communication process requires a medium either analog or digital other than the human or animal communication process semiotically , orally or graphically in text or illustration. Spatially the communication flow can be linear (directional), circular, branched or structured in the path the communication flow. The flow could be direct or relayed.
What is meant by quantization related to communication?
Quantization in communication refers to the process of converting a continuous range of values into a finite set of discrete values. This is essential in digital communication systems, where analog signals must be represented digitally for processing and transmission. By quantizing the signal, we reduce the amount of data needed to represent it, but this can introduce quantization error, which affects the accuracy of the transmitted information. Overall, quantization plays a crucial role in enabling efficient and reliable communication in digital systems.
Compare and contrast PCM and DM?
Pulse Code Modulation (PCM) and Delta Modulation (DM) are both methods of encoding analog signals into digital form. PCM samples the amplitude of the analog signal at regular intervals and quantizes these values into discrete steps, making it more accurate and less prone to distortion. In contrast, DM encodes the difference between successive samples, resulting in a simpler implementation but potentially lower fidelity and higher sensitivity to noise. While PCM generally offers better sound quality and requires more bandwidth, DM is more efficient in terms of data rate but may introduce quantization error.
What are the factors affecting the choice of modulation type?
The choice of modulation type is influenced by several factors, including bandwidth requirements, signal-to-noise ratio, and the nature of the transmission medium. The application context, such as whether the communication is analog or digital, also plays a crucial role. Additionally, considerations like power efficiency, complexity of the modulation scheme, and resistance to interference or fading can impact the decision. Ultimately, the goal is to optimize performance while meeting the specific needs of the communication system.
Which card sends digital information over a phone line to connect to the Internet?
The card that sends digital information over a phone line to connect to the Internet is called a modem (modulator-demodulator). It converts digital data from a computer into analog signals for transmission over phone lines and then back into digital data for the receiving device. Modems can be internal (installed inside the computer) or external (connected via USB or serial ports).
What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
Difference between an analog and digital scope?
Analog can reach higher speeds.
What is the difference between analog and digital altimeter?
Analog is displayed in a clock like instrument digital is shoun in numbers
Difference between analog audio and digital audio?
In analog ckt there is more distortion but in digital there is no distortion. Analog is a continues value digital is a discrite value(0 or 1). To measure analog is very difficult but in digital it is very easy. compare to analog the digital system is very compart for us. H.L.Kiran
what's the difference between analog and digital watches?
Analog is a clock with the moving hands on it, while digital is computer generated numbers.
Whats the difference between analog and digital signal?
Analog signals are continuous while digital signals are discrete
Why you use analog communication?
Because I am an analog creature living in an analog world. If I were a computer I would use digital communication. :-/ ?
What is the difference between a modem and a codec?
* Codec is for coding analog data into digital form and decoding it back. The digital data coded by Codec are samples of analog waves. * Modem is for modulating digital data into analog form and demodulating it back. The analog symbols carry digital data.
What is the difference between digital and analogs?
In chemistry, analog is a compound with a molecular structure closely similar to another. Analog is also relating to or using signals or info represented by a continuously variable physical quantity such as spatial position or voltage. Analog is often contrasted (opposite) of DIGITAL --like a clock showing the time represented by "hands" instead of being Displayed DIGITS.
What is the difference between analog and digital communications?
Analog means continuous transmission of data whereas digital means discrete transmission of data. In analog communications we are transmitting finite amount of data in infinite amount of information. so,there is a possibility of occurrence of noise. where as in digital we are transmitting finite amount of data in finite amount of information. so , out of these two, digital is most efficient.
