Abstract
Филтърът е приложим в електрониката при обработка на цифрови сигнали, получени при преобразуване на аналогови сигнали, съдържащи нежелани съставки при 50 или 60 нz. Той има опростена конструкция и регулируема структура с възможност за потискане усилването на шума. Филтърът съдържа входящ възел и филтър с изцялопропускаща схема, свързан към този възел и включващ поне един закъснителен елемент и поне едно умножително устройство с коефициент на умножение к1. 8 претенции, 3 фигуриThe filter is applicable in electronics when processing digital signals obtained by converting analog signals containing unwanted components at 50 or 60 nz. It has a simple design and an adjustable structure with the ability to suppress noise amplification. The filter comprises an input node and an all-pass circuit filter connected to this node and including at least one delay element and at least one multiplier with a multiplication factor k1. 8 claims, 3 figures
