A novel approach to design Tunable Dual-Band Band-Stop filters will be presented in this paper. These filters have a new configuration with a coplanar microstrip line loaded with SteppedImpedance Resonators (SIRs). These can be tuned by using tuning elements such as a tuning diode and ferroelectric capacitor. The Dual-Band Band-Stop Filter (DBBSF) and Dual-Band Band-Pass Filter (DBBPF) have bec...

An electrocardiogram (ECG) is a medical test that records the normal and abnormal condition of heart. It an essential tool for identifying vari- ous cardiac related issues. However, ECG wave are often distorted by diverse noise sources, such as movement artifacts or electrical interference. To remove these enhance quality signal, various filters commonly used. The choice filter type depends on ...

Packet demultiplexing and analysis is a core concern for network security, and has hence inspired numerous optimisation attempts since their conception in early packet demultiplexing filters such as CSPF and BPF. These optimisations have generally, but not exclusively, focused on improving the speed of packet classification. Despite these improvements however, packet filters require further opt...
