What is the use of connecting an integrator in delta modulation?
Manasasindhuri
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 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 square law diode modulator?
Methods of amplitude modulation can be put in the two categories namely Linear modulation methods and Square law modulation methods. Linear modulation method utilizes the linear region of the current voltage characteristics of the amplifying device that is transistor or electron tube. Square law modulation method utilizes the square law region of some current voltage characteristics of a diode or transistor or electron tube. A large number of linear modulation methods have been devised and have been used to varying degree. These methods are namely linear shunt plate modulation or anode choke modulation, linear series plate modulation, grid bias modulation, cathode modulation, suppressor grid modulation, screen grid modulation, collector modulation. Square law modulation circuits make use of non linear current voltage characteristics of diodes or triodes and are in general suited for use at low voltages. Important square law modulation methods are square law diode modulation and balanced modulator.
Why amplitude modulation is used for video transmission?
IF we use frequency modulation for transmitting video signal this can cause phase shifting .and eyes can percieve this distortion effect easly . and requires more bandwidth to send the signal .Color levels are adjusted by amplitude in TV .So it s more logic to use Amplitude modulation .
Application of pulse width modulation?
PWM finds use in power applications like dc motor speed control
Where is the use of earth transformer?
It is used in where the transformer are connected in star delta.
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
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 are applications of delta modulation?

Why do you use delta-sigma modulation instead of delta modulation?
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 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.
