Electronic-design-automation (EDA) software developer AWR announced that its Microwave Office software design suite now features a breakthrough in filter design recently released by partner Nuhertz Technologies, whose filter synthesis and analysis software, Nuhertz Filter, can be seamlessly integrated within Microwave Office software. The breakthrough is called "delay equalization with off-axis quadruplet and real zeros" and it reduces the computational time needed to obtain flat group delay response in quadruplet zeros delay equalized lumped element filters, from hours to mere seconds. Flat group delay ensures that different-frequency signals are not delayed independently within a filter; it is essential for minimizing signal distortion in communications systems. Nuhertz Technologies has developed a rapid, direct-synthesis strategy for determining the element values that control the low-pass or high-pass quadruplet zeros that influence group delay.
