| | National Instruments Presents Generating of Arbitrary Waveform | | National Instruments today announced two new 200 modular instruments of Mmuestras/s that extend the capacity of measurement of products of mixed signals of the company. The new modules, based on the architecture of Nucleus of Synchronization and Memoria (SMC), duplicate to the reason of sampling and the depth of memory available in the product families of arbitrary waveform generator and digitizer. When being combined with digital instruments PXI of precision for DC, RF and of high speed of National Instruments, the new modules are ideal for a variety of applications in the industries of electronic of general consumption, semiconductors, Armed Forces - aviation and scientific research. | | Leer la noticia completa | Domingo, 31 Octubre, 2004 - 11:00 | |
| | | Ya está aquí WiMax, el futuro inalámbrico | WiMax es la nueva tecnología que transportará los datos por el aire de nuestras ciudades. El interés de empresas como Intel, Nokia o Fujitsu, refuerzan lo que ha dejado de ser un rumor.
La informática es un Formula 1 perfectamente engrasado que no devora kilómetros sino novedades. Gracias a la ley de Moore comprobamos como cada año y medio los procesadores duplican su potencia de proceso, cómo el número de transistores integrados en una tarjeta gráfica son cada vez más numerosos o cómo las memorias flash tendrán, en los próximos 12 meses, un protagonismo similar al de los discos duros de sobremesa gracias a versiones de 16 y 32 Gigas por tarjeta. | | Leer la noticia completa | Miércoles, 27 Octubre, 2004 - 11:00 | |

| | | The Operational Amplifiers | | In 1965, Semiconducting the Fairchild company introduced in the market uA709, the first monolithic op amp widely used. Although it enjoyed a great success, this first generation of op amps had many disadvantages. This fact lead to make an improved op amp, uA741. Because he is very cheap and simple to use, uA741 has been an enormous successful. Other designs of the 741 have appeared from then in the market. For example, Motorola produces the MC1741, Semiconducting National the LM741 and Texas Instruments the SN72741. All these op amps is equivalent to uA741, since they have the same specifications in his leaves of characteristics. In order to simplify the name, most of people it has avoided the area codes and to this op amp of great use it is called 741 simply to him | | Leer la noticia completa | Sábado, 23 Octubre, 2004 - 01:13 | |
