Delta sigma modulation achieves "noise shaping" that essentially high-pass filters the quantization noise. This reduces the noise power in the baseband so that oversampling can access more bits of useful signal resolution than would be possible in the presence of the unfiltered noise.

What is direct FM transmitter?
A simple implementation of FM where no "up conversion" and complex modulation circuitry is needed. One approach is to use a voltage controlled oscillator (VCO) set at a certain frequency by the appropriate voltage level. The desired signal to be transimitted is put on this voltage level which causes the VCO to deviate. This deviation is now classified as freqency modulation.
What do finnish people use instead of a pound?
The gram.
How do you get different colored patapons in patapon the psp game?
U use differerent matierials etg. instead of 'Wood Branch' use 'Hinoki' or instead of 'Cafiteria Meat' use 'Succulent Meat' etc.
The use of figures instead of words in sentences?
If one chooses to use figures instead of words in a sentence/paragraph one must be consistent. That is use ONLY figures or ONLY words and do not mix them both.
Amplitude modulation compared to Pulse position modulation'?
Amplitude modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. AM works by varying the strength of the transmitted signal in relation to the information being sent. For example, changes in the signal strength can be used to reflect the sounds to be reproduced by a speaker, or to specify the light intensity of television pixels. (Contrast this with frequency modulation, also commonly used for sound transmissions, in which the frequency is varied; and phase modulation, often used in remote controls, in which the phase is varied) In the mid-1870s, a form of amplitude modulation-initially called "undulatory currents"-was the first method to successfully produce quality audio over telephone lines. Beginning with Reginald Fessenden's audio demonstrations in 1906, it was also the original method used for audio radio transmissions, and remains in use today by many forms of communication-"AM" is often used to refer to the mediumwave broadcast band (see AM radio). Pulse-position modulation (PPM) is a form of signal modulation in which M message bits are encoded by transmitting a single pulse in one of 2M possible time-shifts. This is repeated every T seconds, such that the transmitted bit rate is M/T bits per second. It is primarily useful for optical communications systems, where there tends to be little or no multipath interference.
Why do you use sigma delta modulation instead of adaptive delta modulation?
if we need simple transmitter and receiver, if we need low bandwidth
What is the Use of Delta modulation?
Delta is a plane company so
What is use of time delay in adaptive delta modulation?
It is used to delay the modulation
What are applications of delta modulation?
Delta modulation is extremely important for high-tech lives that humans live today. Delta modulation is basically analog to digital and digital to analog signal providers, allowing for radio communication devices such as TV remotes.
What is the use of connecting an integrator in delta modulation?
integrator converts the quantised signal to saw tooth signal which then compared with the present signal and error signal is generated,and error signal is quantised and the process continues
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
What modulation does bluetooth use?
It uses GFSK (Gaussian Frequency Shift Keying) modulation technique.
Use delta in a sentence?
you can use delta in a sentence likewhat is deltahow can delta be useor like delta is important to somethings
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.
