WebCap Rate相当于当前回报率的一个“快照”，多数时候Cap Rate是指“初始”回报率，即预估的拥有该地产后前12个月的回报率。 但有时Cap Rate也指过去12个月的回报率，即“历史”回报率。 WebFFR即美国联邦基金利率（Federal funds rate），就是美国金融机构间的拆借利率，可以理解为商业银行之间借钱的利率。 美联储会公布联邦基金目标利率，目标是一个区间范围。
什么是churn rate？其计算公式/方法是怎样的？ - 睿珑学苑
WebThe maximum Chirp Rate is 80 MHz/uSec: 80 MHz/uSec > Chirp Deviation / pulse width. For example, a pulse width of 0.1 uSec and a Chirp Deviation of 4 MHz has a Chirp Rate of 80 MHz/uSec. (2x4MHz)/0.1 uSec. Chirp direction can be ascending or descending and indicates an increase or decrease in frequency during the FM chirp.

什么是chirp信号？_百度知道
A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications … See more The basic definitions here translate as the common physics quantities location (phase), speed (angular velocity), acceleration (chirpyness). If a waveform is defined as: See more A chirp signal can be generated with analog circuitry via a voltage-controlled oscillator (VCO), and a linearly or exponentially ramping control voltage. It can also be generated See more Chirp modulation Chirp modulation, or linear frequency modulation for digital communication, was patented by Sidney Darlington in 1954 with significant later … See more • Online Chirp Tone Generator (WAV file output) • CHIRP Sonar on FishFinder • CHIRP Sonar on FishFinder See more Linear In a linear-frequency chirp or simply linear chirp, the instantaneous frequency $${\displaystyle f(t)}$$ varies exactly linearly with time: $${\displaystyle f(t)=ct+f_{0}}$$, where See more A chirp signal shares the same spectral content with an impulse signal. However, unlike in the impulse signal, spectral components of the chirp signal have different phases, i.e., their power spectra are alike but the phase spectra are distinct. Dispersion of … See more • Chirp spectrum - Analysis of the frequency spectrum of chirp signals • Chirp compression - Further information on compression techniques • Chirp spread spectrum - A part of the wireless telecommunications standard IEEE 802.15.4a CSS See more WebJan 12, 2024 · Churn rate，有时也叫customer churn rate，它是一个常用的英文商业用语，对于企业顾客的管理有着重要意义。下面睿珑学苑给大家快速介绍churn rate的意 … Web经济周期理论中的利率指的是短期无风险利率。美国数据中与之对应的可以是fed funds rate、3个月的treasury yield。这些都是名义利率，真实利率并没有完美的直接数据。 其他语境下的利率就视情况而定了。各种债券、贷款的利率都可以叫利率。 can glycerin cause allergic reaction
