2017年11月8日 — 3dB頻寬 · 資料有數量級的差異時，顯示對數可以同時顯示很大的資料和很小的資料。 · 資料有指數增長或冪定律的特性時，有對數尺度可以將曲線變為直線表示。 ,The half-power or 3-dB bandwidth is the width of the range of positive frequencies where a peak value at zero or infinite frequency (low-pass and high-pass signals) or at a center frequency (bandpass signals) is attenuated to 0.707 the value at the peak. ,The half-power point is the point at which the output power has dropped to half of its peak value; that is, at a level of approximately -3 dB. ,The 3 dB bandwidth is one measure of the range of electrical frequencies a system supports. Input signal frequency components in this range are minorly ... ,2019年4月1日 — Rise time and 3 dB bandwidth are parameters important for characterizing the performance of many electrical and electro‐optical systems. ,2022年8月10日 — -3dB bandwidth simply means the range of frequencies within which the response of the system is greater than -3dB from some datum level. ,2019年11月4日 — The frequency at which the power level of the signal decreases by 3 dB from its maximum value is called the 3 dB bandwidth.,2020年7月28日 — The 3dB bandwidth is the difference between the frequencies between the points which are 3dB down from the peak on both sides. ,半能點（half-power point）或半能頻寬（half-power bandwidth）是輸出功率降到其最大值一半的點，大約是-3 dB的位置。 濾波器、濾光器、放大器電路常以半能點的頻率為其 ...
