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 ...
Abstract Interference signals degrade global navigation satellite system (GNSS) performance and must be mitigated. Chirp can mitigated with an adaptive notch filter (ANF), but the dynamic behavior limits performance. An ANF determines instantaneous frequency removes interference a filter. However, there are several limitations. In this article, we propose multi-parameter (MPANF) approa...
When designing a lowpass filter to eliminate noise in a triangle mesh, the cutoff frequency is typically chosen by a cumbersome trial-and-error process. Therefore, it is important to provide a guideline in selecting filter frequencies. Here, we explore the relation between the frequencies in a mesh filter and the geometric measures of user-selected features. In addition, by combining previously...
The paper presents a current tunable multifunction filter using current conveyor. The proposed circuit can be realized as on chip tunable low pass, high pass, band pass and elliptical notch filter. The circuit employs two current conveyors, one OTA, four resistors and two grounded capacitors, ideal for integration. It has only one output terminal and the number of input terminals may be used. F...
