Abstract
Данное изобретение обеспечивает способ и устройство для распределения импульсов сигнала с широтно-импульсной модуляцией по временному периоду. При применении к цифровому дисплею изобретение обеспечивает сигнал, представляющий цифровые данные, содержащие множество меньших импульсов, распределённых по временному периоду обновления, для управления элементом дисплея. Предусматривается логическая схема для генерирования множества комбинируемых сигналов, чтобы поступающие данные могли комбинироваться с сигналами для определения смеси сигналов, генерируемой в качестве конечного выхода. Отдельные сигналы генерируются путём идентификации активного бита самого низкого порядка счётчика, то есть подразделения подходящего временного периода на меньшие временные подразделения, и генерирования импульса на одном из множества выходов, при этом каждый уникальный идентифицированный бит самого низкого порядка выводится на отдельный выход, а последующие идентифицированные общие биты самого низкого порядка генерируют импульсы на том же выходе.Международная заявка была опубликована вместе с отчетом о международном поиске.
