To remove low-frequency noise from data such as DC-bias from electromyo-grams (EMGs) or drift from force transducers, a high-pass filter was constructed from a low-pass filter of known characteristics. A summary of the necessary steps required to transform the low-pass digital were developed. Contaminated EMG and force platform data were used to test the filter. The high-pass filter successfully removed the low-frequency noise from the EMG signals. The high-pass filter was then cascaded with the low-pass filter to produce a band-pass filter to enable simultaneous high- and low-frequency noise reduction.

This paper describes an overview of data security algorithms and its performance evaluation. AES, RC5 and SHA algorithms have been taken under this study. Three different types of security algorithms used to analyze the performance study. The designs were implemented in Quartus-II software. The results obtained for encryption and decryption procedures show a significant improvement on the performance of the three algorithms. In this paper, 128-bit AES, 64-bit of RC5 and 512-bit of SHA256 encryption and Decryption has been made using Verilog Hardware Description Language and simulated using ModelSim.

Fourier transform profilometry in 3-D measurement based on wavelet digital filter is presented in this paper. Before phase demodulation, original modulated grating image is handled with wavelet transform in order to remove the background components and high frequency. This method resolves spectrum overlapping at some extent and reduces the requirement of low-pass filter.

A phase shift signal generator which has high precision and whose phase can be easily and digitally controlled is designed through utilizing DDS technology. A method which can replace complicated hardware description language programming through calling modules and setting parameters is proposed. The designed phase shift signal generator passes waveform simulation under Simulink and SignalTap Ⅱcertification, and the results obtained on the FPGA board are correct. The DSP Builder is utilized to design the phase shift signal generator, which reduces the difficulty of the design and shortens the design time.

In this paper, we study the implements a data rate can be adjusted, m series can be equipped with pseudo-random series of sequence generator. This design in the basis of linear feedback shift register, through the linear feedback function to produce mould the longest m sequence. In order to carry on it, we use the hardware description language VHDL, take advantage of the FPGA reconfigurability and flexibility, using Quartus II 8.0 for the integrated wiring, and give the Model simulation waveforms. For the sake of verifying the feasibility of this design, we adapt it to the DE2 board, and with an oscilloscope and other equipment were tested.
