What are the advantages of digital modulation over analog modulation?
1)digital modulation can easily detect and correct the noise. where as analog modulation has little complexity 2)security is more in digital modulation 3)digital modulated signal can traverse a long distance compared to analog modulation
Why classb is preferred over class c modulation?
That depends on the use. Each has advantages in different applications. Without more specifics on your application I cannot comment usefully.
What is Advantage of logic analyzer with built in digital pattern generator over simulator?
logic analyzer advantages
What is the advantage of ppm over pwm and Pam?
PPM is a type of pulse modulation where messages are sent using single pulses. PWM is a type of modulation which conforms to the pulse. PAM is a type of modulation in which the information is encoded into a series of pulses.
Why is modulation necessary before multiplexing?
modulation means transmitting the signal which is to be transmitted along with the carrier wave, then at the receiver it is separated from the carrier and demodulated. So modulation is needed so as to transmit the signal over long distances with higher accuracy. Hence it is required before multiplexing.

What are the advantages frequency modulation amplitude modulation?
Frequency modulation have some advantages over amplitude modulation, FM is not sensitive to the amplitude noise, and have high efficient use of transmitted power
Advantages of ask modulation over other digital modulation techniques?
the only advantage is generation of ASK is very much easy. as,it is known as on-off keying. otherwise,it is not advantageous,as,it has highest rate of probability of error......
What is the need of digital modulation scheme?
The aim of digital modulation is to transfer a digital bit stream over an analog bandpass channel, for example over the public switched telephone network (where a filter limits the frequency range to between 300 and 3400 Hz) or a limited radio frequency band.

What is the Digital modulation?
There are 3 main types of digital pulse modulation:Pulse time modulation (PTM), somewhat similar to analog phase modulation.Pulse width modulation (PWM), the width of the pulse represents the signal.Pulse code modulation (PCM), serial transmission of binary bits forming numeric or character codes that represent the signal.All of these can be modulated on an RF carrier using any of the standard modulation techniques: AM, FM, Phase Modulation, etc. One advantage with AM digital pulse modulation techniques over AM analog is that the carrier can be 100% modulated, which cannot be done with analog, thereby allowing significant reductions in transmitter power without loss of coverage range. Sometimes FM digital pulse modulation techniques are referred to as Frequency Shift Keying (FSK). A very complex method of combining Phase Modulation and AM to increase the bit density of digital pulse modulation on an RF carrier is called Quadrature Amplitude Modulation (QAM).

What is hybrid composites and give some advantages of hybrid composites over normal composites?
Combination of two or more materials
What are the advantages of a digital radio over an analog radio?
The advantages of digital radio over analog radio are digital radios get more channels than analog, they are clearer in sound and signal and have more additional features.
Advantages of digital over analog multi-tester?
There are several advantages of digital over analogue multi-tester. The digital multi tester has improved accuracy and is very simple to use unlike the analogue type. .
