I am unsure as to what sigma I should use. When I use the present value of 0.05 all my useful information disappears. From what I understand this means that the signal being removed is all cross-term. Why do I not want this.
Choi–Williams distribution function is one of the members of Cohen's class distribution function. It was first proposed by Hyung-Ill Choi and William J. Williams in 1989. This distribution function adopts exponential kernel to suppress the cross-term. However, the kernel gain does not decrease along the See more The definition of the cone-shape distribution function is shown as follows: $${\displaystyle C_{x}(t,f)=\int _{-\infty }^{\infty }\int _{-\infty }^{\infty }A_{x}(\eta ,\tau )\Phi (\eta ,\tau )\exp(j2\pi (\eta t-\tau f))\,d\eta \,d\tau ,}$$ See more • Cone-shape distribution function • Wigner distribution function • Ambiguity function • Short-time Fourier transform See more WebClassification of Arrhythmia from ECG Signals using MATLAB Priyanka Mayapur Computer Science 2024 TLDR An efficient method to classify the ECG into normal and abnormal as well as classify the various abnormalities is proposed and a comparative study of various methods proposed via different techniques is provided. 10
