What is the difference between pulse code modulation and delta modulation?
The difference between pulse code modulation and delta modulation is that pulse code modulation is a method of encoding audio information digitally while delta modulation is a method that converts analog to digital signal.
What is depth of modulation?
In amplitude modulation, modulation depth refers to the ratio of the unmodulated carrier amplitude to the amplitude deviation for which the modulated carrier wave reaches its minimum value. If this minimum value is zero, the modulation depth is 100%.For amplitude modulation,modulation depth = (a-b)/(a+b),wherea is the unmodulated carrier amplitude, andb is the minimum amplitude deviation.The modulation depth ratio is also referred to as the modulation index.
Where is adaptive delta modulation used?
Adaptive delta modulation is used in audio communication systems to avoid the two drawback of delta modulation.
The amount of frequency shift during modulation is called?
Frequency shift keying in digital communication and Frequency modulation in analog communication..........
What are the three forms of IPv4 communication?
Unicast, Multicast and Broadcast
Why do you use modulation?
MODULATION is a media for transferring information it can come in many forms FM ,AM, PULSES, PAM and so forth.
What are the three types of pulse modulation?
Actually there are four:widthamplitudepositioncodeOf these four pulse code modulation is digital while the other three are analog.
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.
An electric current that is varied to represent information is what?
An electric current that is varied to represent information is called a modulated current. This modulation can take various forms, such as amplitude modulation (AM), frequency modulation (FM), or pulse modulation, and is commonly used in telecommunications to transmit data over long distances efficiently.
What does AM and FM stand for in radios?
AM - Amplitude Modulation FM - Frequency Modulation
Need for modulation?
modulation
What are the two types of angle modulation?
Frequency Modulation and Phase Modulation
When modulation frequency is double the modulation index is halF and the modulating voltage remains constant the modulation system is?
frequency modulation..
How velocity modulation and density modulation related to each other?
due to velocity modulation density modulation occurs in TWT
What is the difference between frequency modulation and phase modulation?
The difference between frequency modulation and phase modulation is that with frequency modulation the angular frequency of the signal is modified while with the phase modulation, the phase angle of the signal is modified.
When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
Why frequency modulation and phase modulation are called angle modulation?
i dont know ans. of this.
