In this note, the presence of impulsive responses in descriptor systems and how it relates to impulse controllability and impulse observability is considered. It is shown that the equivalence between impulse controllability (observability) and the existence of an impulse eliminating semistate feedback (output injection) gain, although true for square descriptor systems, does not hold for rectan...

Abstract—In signal processing, there are mainly two types of filters exist and the are Finite Impulse Response(FIR) filter and Infinite Impulse Response(IIR) filter. Finite Impulse Response(FIR) filter can be designed form Infinite Impulse Response(IIR) filter by various techniques. The widely used technique is the window technique. In this paper, the designing analysis of FIR filter are shown ...

Impulse current generation is required for, o Testing of surge diverters o Testing of non-linear resistors o Electric arc studies o Studies of electric plasmas in high current discharges  For producing impulse currents of large value, a bank of capacitors connected in parallel are c...

Digital waveguide mesh has emerged as an efficient and straightforward way to model small room impulse response because it solves the wave equation directly in the time domain. In this paper, we investigate the performance of the 3-D rectangular digital waveguide mesh in modeling the low frequency portion of room impulse response. We find that it has similar performance compared to the popular ...

A new design of Ultra-Wide band (UWB) generator is described in this paper. The UWB impulse generator circuit is the most essential block in a mono-band UWB transmitter. The proposed ultra wide band impulse generator circuit utilizes the performances of the CMOS technology e®ectively, it is composed of a voltage controlled oscillator (VCO), and a rectangular pulse generator (RPG) and mixer.

A comparison of 4 × 4 multiple-input multiple-output wireless local area network wireless communication characteristics for six different geometrical shapes is investigated. These six shapes include the straight shape corridor with rectangular cross section, the straight shape corridor with arched cross section, the curved shape corridor with rectangular cross section, the curved shape corridor...

A rapid method for calculating the nearfield pressure distribution generated by a rectangular piston is derived for time-harmonic excitations. This rapid approach improves the numerical performance relative to the impulse response with an equivalent integral expression that removes the numerical singularities caused by inverse trigonometric functions. The resulting errors are demonstrated in pr...

Simple computer modeling of impulse responses for small rectangular rooms is typically based on the image source method, which results in an impulse response with very high time resolution. Image source method is easy to implement, but simulated impulse responses are often a poor match to measured impulse responses because descriptions of sources, receivers, and room surfaces are often too idea...

─ This paper presents and evaluates a parallel time domain analysis of a rectangular reflector on multicores machine. Rectangular reflector antennas have motivated the time-domain analysis of electromagnetic scattering problems. The asymptotic time domain physical-optics (TDPO) is applied to the analysis of a rectangular reflector illuminated by a Gaussian-impulse. It is a numerical technique u...
