2024/2/3 -地震のマグニチュード（英: Seismic magnitude scales）とは、地震が発するエネルギーの大きさを対数で表した指標値である。揺れの大きさを表す震度とは異なる。
2024/5/10 -pH、〜等星、マグニチュード、デシベルとか、対数は意外と身近なところにある.
2024/2/19 -The corner frequency associated with poles causes a slope of -20 dB/decade; The final slope of Bode magnitude plot = (Z – P) × 20 dB/decade. Where Z is the ...
2024/3/20 -Simulated results show that the scattering grating lobe of the array with metal walls is suppressed by 5.8 dB at 12 GHz, and the change of radiation performance ...
2024/2/5 -Magnitude response is a measure of how the amplitude of a system's output signal varies with frequency. It is often expressed in decibels (dB) and is used to ...
2024/3/13 -The decibel (dB) is a unit that measures the relative difference between two sound intensities. The relationship is logarithmic: ...
2024/2/19 -In a Bode magnitude plot, which one of the following slopes would be exhibited at high frequencies by a 4th order all-pole system – · -80 dB/dec · -40 dB/dec · +40 ...
2024/4/16 -Hey all, I'm new to this and I was just wondering why I'm seeing people say to normalize to -3 db. On that note, why is it negative db instead of just db?
2024/6/18 -db(k) is the magnitude of repf(k) expressed in dB i.e. db(k)=20*log(abs(repf(k)))/log(10) and phi(k) is the phase of repf(k) expressed in degrees. See ...
