Thank you Omersayli for replying,I have two question then, In level independent all the threshold levels are the same number (one number), while level dependent...
I am a bit confused regarding the thresholding methods and noise estimation options found in Matlab regarding Discrete Wavelet Transform.Please correct me if I am...
So basically it is the same.Got it, thank you for clearing that up.
I understand that in the decomposition process, wavelet and scaling functions are used to split the signal to approximation and detail coefficients.Most of the time...
Yes, I have been using matlab and they have an awesome toolbox for wavelets for some simulations before digging into implementation. Thank you again!
Thank you Bernhard, funny enough I was just saying I should just make my own wavelet and give it my name. I quite liked the wavelet denosing approach since I am...
Yes I do, actually all I have are power-line noises so far and nothing with meaningful signals. I will get in touch to send the data.

Great, thank you! that answers my question.
Thank you dgshaw6 for taking the time and answering both of my posts. My application is intended for real-time.The oscillator approach sounds interesting, is it...
Definitely a typo and I just fixed it, I apologize for the confusion.And got it, harmonics are always a problem.Thank you for the answer.

Wouldn't IIR be a lot more prone to instability than FIR? What benefit would it offer if I used it instead?

Got it, so I am assuming wideband noises would be hard in my adaptive filter

Hello dgshaw6, thank you for the answer! Sorry I didn't provide enough information. My sampling rate is 30kHz, my input signals are physiological signals and many...

Adaptive filter and noise reduction

New thread started 4 years ago
What limitation would I have if my maximum adaptive filter tap order is 8? how can I correlate this to the type of noises the adaptive filter can denoise?Can...
If I had 50Hz noise coming from power line, and signals in the same frequency range (EEG for example 0.1Hz to 100Hz). If my sampling frequency is 30kHz but I downsample...
