### Linear Phase in equiripple filters

Your filter is a linear-phase filter. There are two ways you can define the phase: \begin{align*} H(e^{j\omega}) &= \big|H(e^{j\omega})\big|e^{j\phi_a(\omega)} \\ H(e^{j\omega}) &= A(\omega)e^{...

### First order filters in Direct Form I (RBJ Cookbook)

Okay, I'm gonna try to toss out here my first guess of general 1st-order filters done in the style of the Audio EQ Cookbook. The cookbook assumes the same EE definition of resonant frequency and ...

### Filter secondary bounces of a pulse signal

No, probably not. If your convolutional model was based on the system being excited by your input being a linear one, it is almost certain you'd see negative amplitudes on the output. Your graph doesn'...

### Cross-correlation of two processes generated from the same signal through different LTI systems

You have to work through the calculation once and you'll remember forever. I hope you can fill in the details yourself. First, from the definition of cross-correlation (assuming real-valued filters ...

### Linear Phase in equiripple filters

but do not posses linear phase Incorrect: they do posses linear phase. The problem is most likely with your plotting/visualization code. In order to get a good graph, you often need to zero-pad and ...

### Filtering of sampling effects

With some more researching I looked into how a polynomial can be fitted into the data and used for filtering. Asking this questions to ChatGPT resulted in using a Savitzkyâ€“Golay_filter. While the ...

### Filter secondary bounces of a pulse signal

With the uncertainties involved, no, deconvolution is not something you could apply here. two factors: mismatch of physics and model uncertainty larger than information to the first factor: your ...
