AD7810.doc
DL : 5
AD7810是美国模拟器件公司(Analog Devices)生产的一种低功耗10位高速串行A/D转换器。该产品有8脚DIP和SOIC两种封装形式,并带有内部时钟。它的外围接线极其简单,AD7810的转换时间为2μs,采用标准SPI同步串行接口输出和单一电源(2.7V~5.5V)供电。在自动低功耗模式下,该器件在转换吞吐率为1kSPS时的功耗仅为27μW,因此特点适合便携式仪表及各种电池供电的应用场合使用。

计算离散傅里叶变换的一种快速算法,简称FFT。快速傅里叶变换是1965年由J.W.库利和T.W.图基提出的。采用这种算法能使计算机计算离散傅里叶变换所需要的乘法次数大为减少,特别是被变换的抽样点数N越多,FFT算法计算量的节省就越显著。 -Discrete Fourier transform calculation of a fast algorithm, referred to as FFT. Fast Fourier Transform in 1965 by JW Cooley and TW map out Kormakiti. This algorithm enables calculation of discrete Fourier transform computer required a significant reduction in the number of multiplication, in particular by changing the sampling points N more, FFT algorithm for calculating the amount of savings will be significant.
