spectrum downgrade

The structure of frequency sweep spectrum analyzer Effects of RBW (Resolution Bandwidth) The RBW dictates the resolution bandwidth, which is related to the minimum bandwidth detectable by the instrument. The smaller the bandwidth, the more spectral resolution. However, there is a trade-off between what quickly the display can update the full frequency span under consideration and T He frequency resolution, which is relevant for distinguishing frequen

Learn the guitar for many years, there are always a lot of friends just learn guitar to ask how to practice the guitar, here to share 20 Guitar classic songs Guitar spectrum, to everyone reference practice, these songs are relatively simple, but also absolute classics, including I learned guitar time have practiced, but for just learn the friend is a certain difficulty, So it is certainly going to take a lot of time to learn, including some songs used

When using the js-sdk to collect audio, you want to display the spectrum in real time, but you do not know how to detect the recording parameters in this case. Is there a good way to achieve the desired effect like webaudiodemos. appspot. comAudioR? When using the js-sdk to collect audio, you want to display the spectrum in real time, but you do not know how to detect the recording parameters in this case.

Shannon theorem: c = wlog2 (1 + S/N) or C = WLB (1 + S/N) (LB and log2 are the same)C Indicates the channel capacity, measured in bits per second (B/S)W indicates the bandwidth required for transmitting information. The unit is Hz;S represents the average signal power;N represents the average noise power;Spectrum Efficiency: transmission capability per unit frequency:C/W = LB (1 + S/N)There is a relationship between Shannon theorem and

P68Spectrum: The vast majority of signals can decompose a number of different frequency sine waves, in some sine waves, the lowest frequency is called the fundamental wave of the signal, the rest is called signal harmonics, equivalent to the basic frequency of the signal. The sine wave component, which has a frequency equal to the base frequency integer, is called harmonics.Comparison of image and spectrum after logarithmic transformation of 1.fft2 Ff
