Differentiate between natural sampling and flat-top sampling?
The natural sampling is one which can be represented with respect to amplitude of the analog signal.The flat top sampling is the one which can be represented in only a particular amplitude which cannot be changed with respect to the analog signalthis is true but let me add another difference that Is The Noise ...In Natural sampling : the sample take the top signals shape ( respect to amplitude of the analog signal ) which mean if there is noise above signal , when it will be demodulate with LBF (low pass filter ) it will cut from the original signal ,,,, We cant do that ...but In Flat-Top sampling : the sample shape will be lated so if there is noise we can remove it easily and the signal we be like it transmitted without any noise ...
What is the difference between white Gaussian noise and additive white Gaussian noise?
A Gaussian noise is a type of statistical noise in which the amplitude of the noise follows that of a Gaussian distribustion whereas additive white Gaussian noise is a linear combination of a Gaussian noise and a white noise (white noise has a flat or constant power spectral density).
What is noise triangle?
Noise triangle is a triangular noise distribution for FM.Noise triangle is the study of effect of noise on the carrier signal of the FM wave.
What is the advantage of relative frequency distribution vs distribution frequency?
These help to distribute the frequency much better than the latter. The noise might not be as loud or boisterous this way.
What is noise suppression in digital image processing?
removing noise from digital images. Noise is random color pixels which appears at digital images.

What is noise immunity in digital electronics?
Noise immunity is the ability of a system to perform even when there is noise present. The higher the level of noise a system can still operate under, the higher the noise immunity.
Why flattop sampling is better than natural sampling in a Pam system?
For the generation of a PAM signal we use a flat top type PAM scheme because during the transmission,the noise is interfered at top of the transmission pulse which can be easily removed if the PAM pulse in flat top.In natural top scheme this is not possible.
If sampling frequency doubles then quantization noise?
reduces
Advantage of using differential Manchester coding than plain Manchester coding?
differential Manchester gives better noise immunity.
Sampling frequency doubles then quantization noise?
quantisation noise decrease and quantization density remain same.
Which logic family has the highest noise immunity?
Each logic family has a noise margin (also called "noise immunity") specified by the manufacturer. Manufacturers guarantee that the digital logic will still produce correct results even when some small amount of noise is superimposed on a gate output signal. The maximum amount of such noise that manufacturers are willing to guarantee is the noise margin. In order from highest to lowest noise immunity: high-threshold logic: ??? CMOS has a noise margin of 2.95 volts with a 10 V power supply. CMOS has a noise margin of 1.45 volts with a 5 V power supply. CMOS has a noise margin of 0.6 volts with a 3 V power supply. TTL has a noise margin of 0.3 volts. integrated injection logic (IIL): ???
Why noise immmunity is more in integrator than differentiator?
noise is a ac signal(high frequency range), as LPF allows only lower frequencies integrator is has more noise immunity than differentiator
In an amp What is better high or low signal to noise ratio?
Signal to noise ratio is the difference between the noise floor and the reference level.
What offers better noise isolation, over the ear or earbuds?
Over the ear offers better noise isolation.
What is the natural sources of noise?
All sources of noise are natural. Noise is otherwise defined as soundwaves, which vibrate through matter until they reach your eardrums and the energy used to cause the vibrations is translated into noise by your brain -the pitch is determined by the frequency of the vibrations-. Anyway, it does not matter how the soundwaves are created, it is all natural. You cannot create synthetic noises as far as the physics are concerned.
Is there a better form of Dolby Noise Reduction available?
Dolby noise reduction is currently the standard, and no better commercial alternative exists.
