Vista is a personal-oriented operating system, and its network functions are of course not as powerful as those of the Server version. But let's not underestimate it. In fact, many practical network tools have been integrated in Vista. The full use of these tools will greatly improve your network experience in Vista. Next, let's take a look at these

In the process of acoustic signal processing, we often encounter the following concepts: energy spectrum, power spectrum, octave spectrum,1/3 frequency range spectrum. There are differences and links between these concepts. Some of these concepts are often mixed when people talk about problems. A little bit of time lat
1. Energy and Power Signals
If the energy of the Signal Integration can be obtained, instead of infinity, that is, the energy is limited, and the average power in all time is 0, the signal is an energy signal. If the energy is infinite, the power is used to describe the energy of the signal, which is the power signal. Any signal is either an energy signal or a power signal, because the power of the signal can never be infinite.
2. spectrum, energy
During spectrum analysis, FFT has the following four errors:
(1) spectrum mixing: The nequest theorem has been well known, so almost everyone knows that in order to avoid spectral mixing, theoretically the sampled spectrum is greaterThe highest frequency of the signal. What is the relationship with the time domain?
The reciprocal of the sampling period is the
Spectrum:
The dynamic signal is analyzed in the frequency domain. The analysis result is the spectrum lines and curves of various physical quantities coordinate by frequency, and the spectrum function f (ω) with various amplitude as the variable can be obtained ). The spectrum is a very rigid thing. It often refers to
Spectrum Analyzer is the use of frequency domain to analyze and study the signal of a measuring instrument, for signal analysis it is indispensable, with the rapid development of communication technology, more and more field operations need to support the spectrum instrument (Spectrum Analyzer type), such as communication transmitters and interference signal meas
