What is the modulation?
Phase modultion is one of the three ways of modulating or altering a signal so that it is able to carry information. The other two are amplitude and frequency modulation. Phase modulation is used in high speed modems.
Apakah perbedaan antara analog dan data digital secara umum?
apa perbedaan antara data analog dan data digital
Is sine wave used in analog or digital?
No and yes. Digital signals are usually square or pulse waves. By Fourier analysis, however, every periodic wave, even a square wave, is the summation of some series (often infinite) of sine waves.
How can you transmit voice signal using ask modulation?
The only way is to digitize the audio signal and send it as data
What is signal modulation?
modulating signal is the message to be carried by the carrier signal.
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 is adaptive 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.

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.

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.
What is the alteration called when digital or analog signals are altered to represent binary data?
Modulation
What is the difference between BPSK and DPSK?
BPSK=> 1.The BPSK stands for “Binary Phase-shift keying”. 2.DPSK is a not a method of BPSK, where there is no reference phase signal. 3.amplitude shift keying 4.lesser bandwidth more probability error DPSK=> 1.The DPSK stands for “Differential phase-shift keying”. 2.DPSK is a method of BPSK, where there is no reference phase signal. 3.It is one type of phase modulation used to transmit data by altering the carrier wave’s phase. 4.greater bandwidth probability error less
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
What is modulation in data communication?
Data modulation is a method of Electronic packing of data. In Data communication data is transmitted through a process which is called "Data Modulation".
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
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.
