What is the relation between the path difference and phase difference?
Relation between phase difference and path difference is path difference/wavelength=phase difference/2*pi
What is the difference between nano anatase and nano rutile?
The difference in the crystal structure of the anatase phase and rutile phase
What is the difference between constructive and destructive interference?
Interference is constructive if the phase difference is zero degrees and destructive if the phase difference is 180 degrees.
What is the difference between 1 2 and 3 phase?
There are many different phases. What kind of phase are you interested in?
Difference between absolute PSK and differential PSK?
In abs. PSK only instant phase for the incoming bits are considered. For DPSK, the difference between previous phase and the present phase is considered. Example: If BPSK is used, then for 0 if phase if pi and for 1 it is 0, then for abs. BPSK the phase states for the bit stream 1010 will be 0,pi,0,pi for DPSK, we assume initial phase is zero and a rule that , if incoming bit is zero, then phase difference is 0 and if it is 1 then, phase difference is pi. So, phase difference will be--pi,0,pi,0 Instant phase will be, pi,pi,0,0....Easy!!
What is the relation between the path difference and phase difference?
Relation between phase difference and path difference is path difference/wavelength=phase difference/2*pi
What is the difference between double sampling and multiphase sampling?
DOUBLE SAMPLINGDefinition:A standard form of sample design for industrial inspection purposes. In accordance with the characteristics of a particular plan, two samples are drawn, n1 and n2, and the first sample inspected. The batch can then be accepted or rejected upon the results of this inspection or the second sample be inspected and the decision made upon the combined result.Context:The term has also been used somewhat loosely for what is called multi-phase sampling and the two-stage version of multi-stage sampling. There is a further usage whereby a first sample provides a preliminary estimate of design parameters which govern the size of the second sample to achieve a desired overall result.MULTI-PHASE SAMPLINGDefinition:It is sometimes convenient and economical to collect certain items of information from the whole of the units of a sample and other items of usually more detailed information from a sub-sample of the units constituting the original sample. This may be termed two-phase sampling, e.g. if the collection of information concerning variate, y, is relatively expensive, and there exists some other variate, x, correlated with it, which is relatively cheap to investigate, it may be profitable to carry out sampling in two phases.At the first phase, x is investigated, and the information thus obtained is used either (a) to stratify the population at the second phase, when y is investigated, or (b) as supplementary information at the second phase, a ratio or regression estimate being used.Two-phase sampling is sometimes called "double sampling".Context:Further phases may be added if desired. It may be noted, however, that multiphase sampling does not necessarily imply the use of any relationships between variates x and y. The expression is not to be confused with multi-stage sampling.
What is the difference between multiphase sampling and multistage sampling?
in multi-stage sampling the population is divided into a nonumber of units & in multi-phase sapling when certain items of information are collected from all the units in a sample and other itemsof usually more detailed information are collected from the subsample of the units composing the original sample.
Is there a difference between three phase and single phase electrical supplies?
Yes, there a difference between three phase and single phase electrical supply services.
How do you measure phase difference between 2 pendulums?
You can measure the phase difference between 2 pendulums by measuring the distance between the two. The amount it comes out to will be the difference.
What is the difference between cw and steady at lock-on phase?
What is the difference between cw and steady at lock-on phase? I don't know.
What is difference between a phase and a phase transition?
a phase is a region with homogeneous (uniform) properties and a conversion between states is called a "phase transition"
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
What is the difference between nano anatase and nano rutile?
The difference in the crystal structure of the anatase phase and rutile phase
What is the difference between energy investment phase and energy payoff phase?

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.
What is multi-phase research?
Is the similar to mult-stage sampling but only different is that insteady of conducting in lastly stage but mult-phase conducted in every phase and this type of sampling is applicable in a big organization which is enough fund.
