Аннотация:The delta-compensation sampling process is sampled at the same low rate as reported algorithmic sampling processes and it features a similar low total harmonic distortion (THD). We describe the design of a micropower digital pulsewidth modulator (PWM) for a hearing instrument Class D amplifier. The pulse generator is based on a hybrid 9-b counter 3-b tapped-delay-line. Its arithmetic computation is however, substantially simplified. The PWM embodies a novel delta- compensation sampling process and a novel pulse generator. The complete proposed PWM features a simple circuit implementation, micropower low voltage operation, low sampling rate and low harmonic distortion, thereby rendering it suitable for a practical digital hearing instrument. We investigate the compromise between the different design parameters that affect its power dissipation and THD. We analytically derive the double Fourier series expression and show that the THD is low.

Шины

При использовании слота для обмена по шине: Подсистема PCI I/O должна разрабатываться под напряжение 3.3V c возможностью функционирования при 5 V. Поддержка 64-разрядного или 66 MHz режимов не требуется. Карты Low Power могут потреблять 25-50W, поэтому для обеспечения охлаждения спецификациятребует наличия одного свободного слота PCI. При этом все re ail-карты AGP Pro должны иметь специальную накладку шириной соответственно в 3 или 2 слота, при этом картаприобретает вид достаточно устрашающий. В общем, как представлю себе графическую станцию с двумя процессорами Xeo и видеокартой AGP Pro High Power. Можно здоровосэкономить на отоплении. Закрадывается крамольная мысль, что в спецификацию PC 200? будет заложено жидкостное охлаждение. Опять-таки поживем – увидим Шина USB (U iversal Serial Bus) Что такое USB? Спецификация периферийной шины USB разработана лидерами компьютерной и телекоммуникационнойпромышленности -- Compaq, DEC, IBM, I el, Microsof , EC и or her elecom -- для подключения компьютерной периферии вне корпуса машины по стандартуplug' 'play, в результате отпадает необходимость в установке дополнительных плат в слоты расширения и переконфигурировании системы.
