The radially averaged power spectrum (RAPS) is the direction-independent mean spectrum, i.e. the average of all possible directional power spectra. This function computes and plots the RAPS of an input image. The function was written to produce the RAPS for square weather radar reflectivity images so you will have to relabel the plot axes and title to suit your needs. The radially averaged power spectrum provides a convenient means to view and compare information contained in 2D spectra in 1D

當(dāng)今電子系統(tǒng)如高端處理器及記憶體，對(duì)電源的需求是趨向更低電壓、更高電流的應(yīng)用。同時(shí)、對(duì)負(fù)載的反應(yīng)速度也要提高。因此功率系統(tǒng)工程師要面對(duì)的挑戰(zhàn)，是要設(shè)計(jì)出符合系統(tǒng)要求的細(xì)小、價(jià)廉但高效率的電源系統(tǒng)。而這些要求都不是傳統(tǒng)功率架構(gòu)能夠完全滿足的。Vicor提出的分比功率架構(gòu)(Factorized Power Architecture FPA)以及一系列的整合功率元件，可提供革命性的功率轉(zhuǎn)換方案，應(yīng)付以上提及的各項(xiàng)挑戰(zhàn)。這些功率元件稱為V•I晶片。

The PCA9534 is a 16-pin CMOS device that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-bus/SMBus applications and was developed to enhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvements include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, 400 kHz clock frequency, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc.
