DSP systems

For the digital processors, the peaking time can be taken as the sum of the rise time and the flat top width. The overall peak width is then that time plus the fall time, which is always equal to the rise time Tp = T se + flat top and 7(v — 2 X Tpigg -I- gp. In digital systems, the digitization is concomitant with the pulse reception and we would not expect it to make a separate contribution to Equation (14.6). should, therefore, always be zero.

A DSP system begins at the conversion from the analog input and ends at the conversion from the output of the processing system to the analog output as shown in the figure... 

Let us consider the accuracy required for the sampling clock in a DSP system, van de Plassche has the following analysis If the input is full range and near the Nyquist frequency, then we have the greatest slope. Let us use a simple sinusoid as the input, i.e., V = A sin (at). The variation in the output of the converter that depends on the... 

This section will be presented in a historical fashion from oldest to newest technology. This will demonstrate the effect of technology on the design and implementation of DSP systems and offer a perspective on the effect of underlying technology on architecture of audio signal processing systems. 

According to all the results of the studies on four-center photopolymerization, the whole reaction scheme of the DSP poly-DSP system is given below showing the typical behavior of photopolymerizable conjugated diolefinic compounds10. ... 

The dyncimics of the photoreactive systems were investigated by two-photon absorption processes. The photopolymerizable a-DSP system was investigated by two-photon absorption process. For this process a dye-laser pumped by the second harmonic of a Nd-Yag laser was used to provide a tunable wavelength range from 600 to 700 nm. Even at...

Besides microsilica, other ultrafine materials may be used as constiments of DSP systems, as long as their particles are small enough to fill the existing spaces left between the particles of cement. Aldridge et al. (1992) produced a DSP material using ultrafine mtile (TiOj) instead of microsilica as filler. The resulting material had properties comparable to those of a DSP product made with microsilica, in spite of the absence of a pozzolanic reaction in this combination of starting materials. 

Tibial fixation is achieved with a modified pullout suture technique using the DSP system at an optional/predetermined amount of the initial tension. According to our cadaveric experiment, the mean laxity match tension for the ART ACLR knees was 8.6 4.8 N, the recommended initial tension to the graft at the time of its final fixation could be reasonably assumed to 10 to 20 N [13].
