Abstract: We present in this paper a powerful low-cost method for real-time digital signal analysis and measurement based Discrete Fourier Transform. This measurement system needs understanding the mathematical background and the computational implementation, using the adequate cables, connectors, as well as having knowledge and experience for interpreting the results obtained. This paper tries to understand the fundamental concepts in DFT-based measurements, providing a better comprehension of the measured parameters, procedures, and interpreting the resulting data. We attempt to make this paper summarized as much as possible; at the same time, to treat the most important aspects showing the different stages implemented into the system developed.

Abstract: This paper proposed a high payload image steganography method based on modulus parts of Kekre’s Advanced Multiple LSB Algorithm (KAMLA) and Lorenz chaotic map. In the proposed method a 256 by 256 color image is embedded in a 512 by 512 cover image with acceptable imperceptibility. Experimental results showed that proposed algorithm sustains a higher confidentiality and still can provide high capacity as compared to KAMLA hiding algorithm.
