Com o alto-falante operando em sistema de alta potência (comum em sistemas de PA), o superaquecimento da bobina e o deslocamento excessivo do cone são as principais causas de danos e falhas. Esses problemas estão relacionados à baixa eficiência

O método de Thiele-Small para projeto de caixas acústicas considera o modelo linear do alto-falante excitado por fonte de tensão, operando com pequenos sinais. Subseqüentes estudos têm sido feitos para introduzir no modelo algumas característic

This paper presents a real-time implementation of self-adjustable analog and digital phase equalizers with reduced computational effort. The proposed approach is based on searching for the slope of a straight line and an error characterizing the undu

This paper presents a two-terminal fault-location method which works with unsynchronized phasors. The algorithm is iterative and takes a distributed line model into account. At each iteration, the voltage magnitudes computed from the voltage and curr

In some recent applications, researchers have been facing old problems of the time-domain synthesis, like the necessity of having circuits providing particular temporal responses. In this paper, we show that a recent method suitable to approximate fu

This paper presents a simplified method for determination of filter functions with simultaneous magnitude and phase specifications. For such, the approximation functions that attend magnitude requirements are cascaded with second-order equalizing ste
