i have facing a problem in wavelet transform ,i want compute spectral energy based on wavelet details from one dimensional signal and display it , but i don't know how do it ? i see an aformula about compute spectral energy in diffrent articles but i don't underestand it ?can anyone help me ?it's very important to display spectral energy based on time.
ther is a photo about spectral energy a signal that comput with details.
hoping for help.
