In Coherent demodulation the incoming signal are in phase with the local oscillator signal. This type of detection used in satellite standards because direct uplink and downlink transmission and reception respectively through earth station hub.
But in non coherent demodulation there is a phase discontinuouty due fading of the channel. This type of detection used in terrestrial applications (mobile wireless standards).

What is the main difference between visible and coherent light?
First let us remove the word visible from this question and replace it with incoherent, as visible light can be either coherent or incoherent and coherent light can be either inside the visible spectrum or outside it.Incoherent light is random/unordered, e.g. wave phases different, shines in all directions, polychromatic.Coherent light is ordered in one or more ways, e.g. wave phases all synchronized, shines in one unidirectional collimated beam, monochromatic.The difference between light in the visible spectrum or outside it is only whether humans can see it or not, there is no difference in the light itself other than wavelength.
What temperature is needed of hardening?
The temperature needed for hardening varies depending on the material being processed. For example, steel typically requires heating to temperatures between 800°C to 1,200°C (1,472°F to 2,192°F) for hardening. In contrast, polymers may need to be cured at much lower temperatures, often around 150°C to 200°C (302°F to 392°F). Always refer to specific material guidelines for precise hardening temperatures.

What is difference between coherent machine and incoherent machine?
The main difference between coherent and incoherent machine is the consistency in performance. A coherent machine has processors that work in a consistent manner.Ê
What is difference between coherent and noncoherent communication?
1) This is an example of coherent communication. 2) Of example this communication an is noncoherent.
What are coherence?
COHERENT WAVESWhen the light waves are emitted from a single source and they have the zero phase difference between them then the waves are said to be coherent. The coherent waves are shown below:
What is the difference between coherent demodulation and non coherent demodulation?
In case of coherent demodulation carrier used for demodulation purpose is in phase and frequency synchronism with carrier used for modulation purpose. For non-coherent demodulation it is not in synchronism.
What are coherent sources Give example.?
Coherent sources are sources of waves that have a constant phase difference between them. An example of coherent sources is two identical lasers emitting light waves with the same frequency and wavelength.

Is there any difference between work hardening and strain hardening?
In strain hardening hypothesis, the size of the yield locus is assumed to beindependent of the third invariant.In work hardening hypothesis, the size of the yield locus is assumed to depend on the total plastic work done (per unit volume) to achieve the present state of plastic deformation since last annealinfor isotropic hardening Both are same.
What is the difference between the efficient market hypothesis the fractal market hypothesis and the coherent market hypothesis?
0 what are characteristics of efficient market hypothesis?
What are coherent sources and conditions for it?
Coherent sources are sources that emit light waves with a constant phase relationship. Conditions for coherence include having the same frequency, wavelength, and waveform, as well as a constant phase difference between the sources. This coherence allows for interference effects to occur, resulting in patterns such as diffraction and interference fringes.
What is the identical light waves in a phase called?
Identical light waves in phase are called coherent light waves. Coherent waves have a constant phase difference between them, which allows for constructive interference and the formation of interference patterns.
