What Is A Spectrum Analyzer And How Does It Work?
A spectrum analyzer is a type of electronic test equipment which measures an electrical, optical or audio waveform. A spectrum analyzer displays the frequency response curve as it occurs in real time. It can also measure the power spectrum when used with an antenna which has been properly calibrated.
There are two types of spectrum analyzers, analog and digital. The analog variety breaks down into two further sub-types. One type works by the means of a variable band-pass filter whose mid-frequency is swept through the range of frequencies to measure in the spectrum. The other type uses a superheterodyne receiver where an oscillator is swept through the range of frequencies to be measured. A digital spectrum analyzer works by computing the discrete Fourier transform (DFT). The DFT is a mathematical formula which transforms a waveform into the components of its frequency spectrum. Due to the superiority of digital technology, a digital analyzer will always outperform an analog analyzer in frequency resolution for a given acquisition time.
Some spectrum analyzers use a method of measurement which combines both the analog and digital methods. In this type of analyzer the incoming signal is down-converted to a lower frequency using superheterodyne techniques and then analyzed using fast fourier transformation (FFT) techniques.
Spectrum analysis equipment, especially optical spectrum analyzers, are widely used in the telecommunications industry to determine occupied network bandwidth. This type of test equipment is also used extensively in the audio industry. One such use is in room conditioning for high end stereo and home theater installs. A spectrum analyzer can pinpoint frequencies to cut or boost to compensate for room conditions thus leading to a more accurate representation of the source audio material. For many reasons they're an indispensable tool in ensuring the accuracy of network communications and audio systems.

Where do you land on the political spectrum? Do the issues drive your philosophy or vice-versa?
This is a fun and interesting little test that will tell you where you stand on the political spectrum philosophically.
http://www.okcupid.com/politics
Does the test place you where you place yourself? Are there any questions that you found particularly interesting and how did you respond?
My results:
You are a
Social Liberal
(80% permissive)
and an...
Economic Conservative
(93% permissive)
You are best described as a:
Libertarian
This was a difficult test, but the results were as expected:
social liberal = 63% permissive
economic liberal = 18% permissive
The final comment was, "You exhibit a very well-developed sense of right and wrong and believe in economic fairness".
It Makes ¢ents to Rent - The Benefits of Test Equipment Rental
Just months after the most recent economic collapse, the global market seems to be stabilizing more quickly than expected. Many high-tech companies have reverted back to a popular method of equipment management implemented in the 1970's: outsourcing. Unlike jobs moving overseas for pennies on the dollar, businesses use third party equipment distributors to manage equipment for R&D companies ...
