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

當今電子系統如高端處理器及記憶體，對電源的需求是趨向更低電壓、更高電流的應用。同時、對負載的反應速度也要提高。因此功率系統工程師要面對的挑戰，是要設計出符合系統要求的細小、價廉但高效率的電源系統。而這些要求都不是傳統功率架構能夠完全滿足的。Vicor提出的分比功率架構(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換方案，應付以上提及的各項挑戰。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.
