Compared to their analog counterparts, digital filters offer outstanding performance and flexibility. Designing digital filters can seem a daunting task, however, because of its seemingly endless ...

If you simulate circuits that include not only analog, but also digital or switching/PWM aspects, then you know that traditional “AC” or frequency-domain analysis cannot be used for these designs.

In today's world of increasing electrical noise, higher-speed logic, and more-sensitive circuits, the need for high-frequency noise filtering is especially critical. Noise can enter a circuit through ...
