In a analog transmitter the RF carrier have to be modulated with the analog signal either by AM or FM where in digital transmitter the carrier is simply switched on and off a off = a zero and on = a one

What Is a Computer modem made of?
A computer modem is made up of various components including a modulator, demodulator, analog-to-digital converter, digital-to-analog converter, signal processor, and a connection interface such as Ethernet or phone line. These components work together to modulate digital data from the computer into analog signals for transmission over a communication medium and then demodulate received analog signals back into digital data for interpretation by the computer.
Which is faster an analog computer or a digital computer?
built with the same level of technology, analog computers are always faster but less accurate than digital computers. however as little significant work on analog computers has been done since the 1980s, they currently significantly lag behind digital computers in speed.
Are most computers analog machines?
No, most computers today are digital machines. Digital computers operate using discrete binary data, represented as 0s and 1s. Analog computers, on the other hand, manipulate continuous physical quantities such as voltage, current, or mechanical motion. While analog computers were used in the past, the vast majority of computers in use today are digital.
What is a computer called with combination of an analog and a digital computer?
hybrid computer
Full meaning of bandwidth?
Measurement of the capacity of a communications signal. For digital signals, the bandwidth is the data speed or rate, measured in bits per second (bps). For analog signals, it is the difference between the highest and lowest frequency components, measured in hertz (cycles per second). For example, a modem with a bandwidth of 56 kilobits per second (Kbps) can transmit a maximum of about 56,000 bits of digital data in one second. The human voice, which produces analog sound waves, has a typical bandwidth of three kilohertz between the highest and lowest frequency sounds it can generate.
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 forecasting?
k,
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
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.
Difference between analog communication and digital communication?
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
Difference between analog digital transduser?
please help me to understand the word transducer
What are the differences between a mounted digital kitchen scale and a standard analog kitchen scale?
The main difference between these scales it that the digital will give a more accurate and easier to read reading than figuring it out with the lines between the numbers the analog scale. However, the digital scale requires and battery and the analog does not.
What is the basic difference between analog and digital system?
analog signals are continuous but digital signals are discreet. Digital signals have only binary value like zero(off state) or one(on state).
