Abstract

Un circutería de filtro FIR para el procesado de señales muestreadas multiplexadas por división de tiempo, que incluye series paralelas de elementos de retardo (Dsp, Dhp), para retardar las señales de retardo respectivas que van a filtrarse, teniendo cada serie una pluralidad de derivaciones. Las derivaciones correspondientes de las series respectivas de los elementos de retardo se acoplan a una estructura común de ponderado (Wn+i) y sumado (adicionadora). Se acopla una señal multiplexada por división de tiempo a series paralelas de elementos de retardo estando las series respectivas (Dsp Clk, Dhp Clk), exclusivamente cronometradas al aparecer las señales correspondientes.
