The overvoltage protection for the multiple individual sensitive loads is complicated to implement, because the protection can be done using the Fuse, stabilizer and other protection equipment which cannot have the speed of operation to protect the sensitive load. In this proposed method, the solution for over volta...

ABSTRACT QUADRATURE PHASE SHIFT KEYING Quadrature Phase Shift Keying (QPSK) is a form of Phase Shift Keying in which two bits are taken at a time and modulated, selecting one of four possible carrier phase shifts (0, 90, 180, or 270 degrees). QPSK allows the signal to carry twice much information than ordinary PSK...
