Such systems play an important role in time-frequency analysis and digital signal processing.
      
There are many advantages in the use of Hadamard matrices in digital signal
      
An Inhomogeneous Uncertainty Principle for Digital Low-Pass Filters
      
This article introduces an inhomogeneous uncertainty principle for digital lowpass filters.
      
The measure for uncertainty is a product of two factors evaluating the frequency selectivity in comparison with the ideal filter and the effective length of the filter in the digital domain, respectively.
      
It is a fact that the feedback delay actually arises in digital control systems.
      
It is necessary to modify the structure of digital control systems and develop new control algorithms, which is done in this paper.
      
A great number of digital computer simulation experiments have shown the obvious advantage of the new algorithms.
      
On the order properties of digital curves in the pan-euclidean geometry
      
We introduce and prove for the first time characterization theorems of the segment code order of digital lines and curves.
      
A digital accelerometer is developed by using a ring oscillator (RO) and a mixer.
      
The mixer is an interior signal processor that improves the output signal characteristics, with the digital output signal representing the frequency change.
      
Digital controller for hybrid filter in HVDC based on approximate inverse system
      
The proposed digital controller is implemented with a TMS320C32 DSP, including a series of parallel digital band-pass filters, phase shifters and amplifiers.
      
The results of both simulations based on PSCAD and experiments on a 30 kVA HVDC system prove that the proposed digital control system is stable and efficient for eliminating the harmonics.
      
Fast identification of digital amplitude modulation level at low signal-to-noise ratio
      
The ADSP-TS101 is a high performance digital signal processor (DSP) with good properties that include parallel processing and a high speed.
      
The digital modulation/demodulation methods are applied to the OFDM algorithm.
      
Positioning models and systems based on digital television broadcasting signals
      
The requirement and feasibility of the positioning system using digital television (DTV) broadcasting signals are analyzed.
