The erase voltage applied to a set of non-volatile storage elements being erased is structured to provide controlled shifts in the threshold voltage of the storage elements. The erase voltage is applied as a series of voltage pulses, when necessary, to shift the threshold voltage of to-be-erased memory cells below a verify level indicative of an erased condition. To avoid over-erasing the memory cells, the second erase voltage pulse is decreased, or not increased, in magnitude when compared to the previously applied voltage pulse. By decreasing or not increasing the size of the erase voltage, the amount of charge transferred from the cells by the second pulse is controlled to more accurately position an erased threshold voltage distribution for the cells near the verify level. Subsequent erase voltage pulses are increased in magnitude to provide further erasing when needed.

The present invention provides a method for correcting a shift of an output wavelength of a light source. The output wavelength shift correcting method derives simple equations through experimental processes, predicts a shift degree of the output wavelength with respect to a varied input current using the equations whenever a drive current is reset later, and adjusts a drive temperature according to the predicted shift degree, thus correcting the shift of the output wavelength. The output wavelength shift correcting method is advantageous in that it provides a method of locking an output wavelength of each light source without continuously operating a wavelength locker or a wavelength measuring device, thus reducing the operating cost of the optical communication system.

The invention relates to a frequency-domain migration-based de-chirping inverse synthetic aperture radar (ISAR) envelope alignment method. According to the method, based on the alignment of a conventional envelope correlation method, the accuracy of envelope alignment is improved by using the frequency-domain migration property of Fourier transform; and the maximum constraint condition of the accuracy of traditional envelope alignment is that the error of migration alignment cannot break through the limitation of half of a range resolution cell when migration alignment is carried out under a condition that time-domain signal sampling is completed, and the solidification of range units is completed, wherein one range unit is one complex data representation. Since FFT operation is required to be carried out before the formation of range units in de-chirping signal processing, echo signals are multiplied by a frequency shift factor before the FFT operation, and accurate migration of data which have been subjected to FFT can be realized.
