In area of Digital Signal Processing, the purpose of filters is to remove the selected range of signal such as noise or to extract meaningful data from the signal. A filter is a device which is designed to pass frequencies within a specific range while rejecting all other unwanted frequencies that fall outside this range. Filters are widely in use in the field of communication and signal processing applications such as radar, video operations, audio processing, ECG, EMG, EEG, channel…

TLDR
An attempt to apply the existing methodologies to Massachusetts Institute of Technology-Beth Israel Hospital noise, stress test database ECG signals and perform a quantitative study based on the performance metrics such as specificity, sensitivity, accuracy, mean square error and signal to noise ratio.

Design and Test of a Microdestructive Tree-Ring Measurement System

TLDR
The annual rings of larch and fir tree discs were measured and tested using the designed system and it was observed that the average annual ring measurement accuracy of the larch discs reached 95.28%, while that of the fir discs was 84.16%.
