why do we need frequency domain?
grid
@pankajkumardas, 

converting geophysical data from the space (or time) domain to the frequency domain (via fast fourier transform) is common practice in geophysics, particularly when wanting to apply some sort of filter to that data. 

we do this because it is more computationally efficient to filter data in the frequency domain compared to the space domain. for example, applying a filter such as a first vertical derivative to a grid of magnetic data in the space domain requires convolution using a two-dimensional filter. depending on the type of filter, that process can be complex and therefore computationally expensive. 

transforming the data and the filter to the frequency domain allows us to simply multiply the two to get a filtered spectrum, which is then transformed back to a filtered grid in the space domain. this process is far more computationally efficient than convolution.

the following diagram describes the distinction between space and frequency domain filtering. it is taken from reeves (2005), which you can access here: http://www.geosoft.com/media/uploads/resources/technical-papers/aeromagnetic\_survey\_reeves.pdf




i'd urge you to download the document and review chapter 6, from which the diagram is taken.

best regards,
five factors are known to affect allele frequency in populations i.e., hardy-weinberg equilibrium. these are gene migration or gene flow, genetic drift, mutation, genetic recombination and natural selection.gene migration or gene flow – it is movement of alleles into a gene pool or out of a gene pool. when this movement of alleles takes place gene frequencies change in the original as well as in the new population. new genes/alleles are added to the new population and these are lost from the old population. this will lead to a gene flow if this gene migration, happens multiple times.genetic drift – if the movement of alleles into a gene pool or out of a gene pool takes place by chance it is called genetic drift. this always influences frequencies of alleles and s inversely proportional to the size of the population. it sometimes result into founder effect i.e., when a small group of individuals get isolated from a larger population to form a new population. genetic drift may result into reduced genetic variation.mutation – is the large difference arising suddenly in a population, they are random and occur in all directions.natural selection – is a process in which heritable variations enabling better survival are enabled to reproduce and leave greater number of progeny. that is nature selects only those traits which help an organism to survive in the changed conditions. those that are not fit for survival perish in the long run leading to evolution of new species.genetic recombination – production of new offspring with traits which differ from parents is called genetic recombination. dear student,

each radio station is given a different frequency band and these
radio signals are sent at that particular frequency only
for example fm 93 5 or 94 3 etc are given radio frequencies given
in decimals only

if we see each radio station contains name like fm 93 5 or 94 3
etc

regards, you have your own domain  

I'm assuming its for Holy Spirit Catholic Church Fountain Valley??  

Your domain probably assigns IP addresses. I highly recommend you get someone with IT networking experience to help you  

I wouldn't want someone not knowing what they are doing playing on my domain  

If you insist you need to do it post back and we can start trhye procedure with no guarantees  

Does the desktop have a wireless network card installed ?lLok at the back and tell me if you see an antenna or is there some cable plugged into a USB port and at the other end have something a little bigger then a Memory stick on the end of it? lol! real soon! that's why we need a republican president. ?answer :
step 1 of 1 :


in a pareto chart, the bars are always arranged in descending order according to frequencies.
the pareto chart helps us understand data by drawing attention to the more important categories, which have the highest frequencies. alphacompounder: 
1. this can be an extremely long answer. i'll keep it short - the opportunity for exposure, meet and work with brilliant minds, put my analytical and logical skills to right use, $ increment from a big4 role.
2. over the years, the team members (10+ years each) have built solid connections in the industry. networking events (eg. superreturn)+ leveraging our personal connects to stay in touch with these gps. we also use databases (eg. a frequency converter, also known as a frequency changer, is a device that takes incoming power, normally 50 or 60 hz and converts it to 400 hz output power. the relationship of wavelength and frequency will appear as:using the wavelength range given, 280-320 nm, frequency range will be calculated using the equation above and by converting the values to the proper units [readmore]each wavelength must be in meters:we need to calculate the frequency for both 280 and 320 nm:range of frequency will appear as 1.07x1015 to 9.38x1014 s-1 please grafting – layering
