Normalized frequency什么意思

WebNormalized Frequency The normalized frequency, or V number, is a parameter used in optical fibers. The normalized frequency is proportional to the radius of the fiber divided by the wavelength times the square root of the difference of the squares of the maximum refractive index of the core and the refractive index of the homogeneous cladding. WebSine sweep was played by a good loudspeaker of which I have the FR specs. Now these FR charts have different "dB ranges": Mic FR: -90dB to -10dB. Speaker spec: starts at -45dB, moves to 85dB and stays mostly linear. The goal is to normalize the mic FR data w.r.t to the speaker's FR spec and then use that result to create an (inverse) FIR filter.

However, doing so for this particular example would produce a normalized frequency larger than 1 for the cutoff high frequency: $$\frac{2 \cdot f_c}{fs} = \frac{2 \cdot 600}{1000}=1.2$$

Web22 de fev. de 2024 · More Answers (3) Normalized frequency is a ratio of a specific frequency (e.g., the cutoff frequency for a filter) to twice the sampling frequency. For example, if the sampling frequency is 8000 Hz, and you want to filter at the 500 Hz point, then the normalized frequency would be 500/ (2*8000) = 5/160. Sign in to comment. Web19 de out. de 2024 · Accepted Answer. This toolbox uses the convention that unit frequency is the Nyquist frequency, defined as half the sampling frequency.
