By properly setting up a secondary sound source on ship's shell, it is theoretically feasible to suppress ship radiated noise in a local region. Since low frequency line spectrum of ship radiated noise contains significant signature information, its active control has always been an important research task. Due to sound interference, to actively control various spectral lines, the phase compensation...
Many islands are far away from areas where power-grid arrives at difficultly in our country. To solve the problems of using electric and of using freshwater, hybrid wind pumped-storage desalination system was brought forward. Intelligent control of hybrid system was studied. The hardware flat of control system was built. The intelligent control strategy was put forward. Using VC#2008 visual interactive...
Area-efficient resistor-capacitor DACs (R-C DACs) and low-offset push-pull output buffers for a 10-bit LCD source driver are proposed. Comparing to a 10-bit resistor-string DAC (R-DAC), the 10-bit R-C DAC has a smaller area. A new output buffer with a push-pull function is adopted so that the source driver can drive the pixel with two-dot inversion to save power consumption. To reduce channel to channel...
