How do you do modulation BPSK with a digital input the modulation must use matlab simulink?

BPSK Modulation can be done by using a multiplier. Digital data must be multiplied with the carrier frequency. In matlab simulink use a multiplier block to one input apply a sinusoidal generator & to the other a Pulse generator


What are the goals for digital modulation?

Simply put, digital modulation is designed to maximize the amount of data we can put through a system per unit of time while maintaining the integrity of that data. Those are the two primary goals.


What is Adaptive delta modulation?

Adaptive delta modulation is a analog-to-digital and digital-to-analog conversion technique which is primarily used for voice transmission data and can be used for multiple purposes.


Difference between delta modulation and differential pulse code modulation?

Delta modulation is not a type of quality conversion and runs on digital-to-analog, analog-to-digital. Differential pulse code modulation has a higher quality of conversion and runs on a 1-bit data stream.


Which modulation is used with digital data?

pam ppm pwm psk etc can be used


Define Data modulation in data communication and networks?

Data modulation is a method of Electronic packing of data. In Data communication data is transmitted through a process which is called "Data Modulation".


What is the difference between encoding and modulation?

Encoding: The way in which the computer data is represented is known as encoding, there are several encoding techniques (Unipolar, Bipolar and Biphase).Modulation: Modulation is the method of changing some of the characteristics of the message signal so that it can be transmitted to comparatively large distance without(least) getting affected by noise or unwanted signals.Encoding: The way in which the computer data is represented is known as encoding, there are several encoding techniques (Unipolar, Bipolar and Biphase).Modulation: Modulation is the method of changing some of the characteristics of the message signal so that it can be transmitted to comparatively large distance without(least) getting affected by noise or unwanted signalsEncoding : Digital or Analog data --> Digital signalmodulation : Digital or Analog data --> Analog signal


Is modem input or output devices?

Both. Modem stands forMOdulator DEModulater.Modulator comes from modulation which is the process of converting analogue data to digital for transmission and Demodulator from Demodulation, converting digital signals to analogue.Digital data-discrete or non-continuous dataAnalogue data- continuous or non-discrete data


Which device connects a computer with a telephone line by providing modulation and demodulation of incoming and outgoing data?

Answer:It's the modem that connects it... It is mainly a combined device for modulation and demodulation. A.K.A digital data of a computer. That is all it is. :D


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 do digital dashboard and data mining applications differ from transaction processing applications?

Digital dashboard and data mining applications do not generate new data, but instead are used to summarize existing data to provide information to management


What is the difference between the AM modulation and ASK modulation?

This is hard to explain. AM means amplitude modulation, while ASK is amplitude-shift keying. AM is usually analog as it is modulated based on the strength of the signal, though you can use it to send a digital signal. ASK represents digital data as variations in the amplitude of a carrier wave. Any digital modulation technique will represent the data using a finite number of different signals. While AM is used mostly for radio and television, ASK is used for telegraph signals, transmission across telecommunications equipment, and fiber optics.


What are Modems used for in Internet?

to convert analog to digitial data and digital to analog. it used in internet modem means modulation demodulation


What has the author Irwin Lebow written?

Irwin Lebow has written: 'The digital connection' -- subject(s): Digital electronics, Popular works 'Understanding digital transmission and recording' -- subject(s): Digital modulation, Sound, Data transmission systems, Recording and reproducing, Digital techniques


Is modulation needed for digital data transmission?

Modulation is only required if the data is being sent over a radio wave, or a laser beam. And even in the case of a laser, if you are content with on/off data streams, then there is no underlying signal to be modulated. Essentially all of the data whizzing round in your computer is doing so without the benefit(?) of a carrier - the wires are sufficient.


Different types of signal encoding technique?

n Digital data, digital signal n Equipment less complex and expensive than digital-to-analog modulation equipment n Analog data, digital signal n Permits use of modern digital transmission and switching equipment n Digital data, analog signal n Some transmission media will only propagate analog signals n E.g., optical fiber and unguided media n Analog data, analog signal n Analog data in electrical form can be transmitted easily and cheaply


Is sine wave used in analog or digital?

Analog and digital transmissions: Carriers in AM, FM broadcast, TV (analog). Modems for data transmission (amplitude, frequency, phase modulation of a sine wave to materialize 1 and 0 bits).


What is the difference between NRZ L and Manchester encoding?

NRZ L: data rate = modulation rate/2 Manchester: data rate = modulation rate

What is modulation in data communication?

Modulation is the combining of an information signal (also known as the modulating signal) with a carrier signal.


What converts analog data to digital data and vice versa?

An analogue-to-digital converter (ADC) is used to convert analogue data into digital data for the computer system to process. A digital-to-anagloue converter (DAC) is used to convert digital data back into analogue data for output.


Explain the term modulation. how does it help in data communication?

Modulation is the addition of information to an electronic or optical signal carrier. The modulation can be applied by turning the signal on and off.


What is encoding technique?

There are four possible combinations of encoding techniques -Digital data, digital signal -Digital data, analog signal -Analog data, digital signal -Analog data, analog signal


What is a data bus?

A data bus is a group of connections running throughout a digital system (e.g. computer) that attaches to all the various units in that digital system that process or generate data (e.g. ALU, memory, register set, I/O devices). Only one unit that is connected to the data bus can be enabled at a time to drive it with a data value. Most digital systems have only a single data bus, but some (e.g. digital signal processing computers) may have more, allowing several different data values to be passed between units simultaneously instead of just one at a time.


What type information system would be recognized by digital system?

A digital system can recognize digital data i.e. data only in form of 0 & 1, if data is not in digital form we have to convert it using analog to digital converters.
