For example, if you choose to participate in write-on, you will be partially judged on the accuracy of your Bluebooking. Similarly, Bluebooking can provide anybody reviewing a writing sample an easy way to make a âfirst cutâ and divide applications between those that will get a closer look and those that will not.
A spectrum analyzer is a device used to examine the spectral composition of some electrical, acoustic, or optical waveform. Often, it measures the power spectrum.
FFT spectrum analyzer. The block diagram and topology of an FFT analyzer are different to that of the more usual superheterodyne or sweep spectrum analyzer. In particular circuitry is required to enable the digital to analogue conversion to be made, and then for processing the signal as a Fast Fourier Transform.
