### RMS of signal vs average amplitude

I am trying to estimate the average amplitude of some signal with frequency 6 Hz, sampled at ~300 Hz. See figures for a part of the signal and its dft calculated using matlab. I estimate the average ...

### How to classify audio files based on their ZCR, energy, and enthropy of energy features?

Let's say I wanna classify the audio files of race car exhaust and normal car exhaust. I attain few features such as ZCR, energy and enthropy of energy from the training set and I wanna build the ...

### How to obtain exponential decay peaks from damped signal in python? [closed]

I have a signal where I would like to implement a peak detection algorithm where it only collects peaks that follow exponential decay behaviour and stop at a certain height. Here is an example of a ...

### When are MLSE (with Viterbi algorithm) equalizer used in real life (only for equalization)? [closed]

The complexity of a MLSE decoder (with Viterbi Algorithm) is in the order of $M^L$, where $L$ is the length of the channel and $M$ is the order of modulation. My question is in what circonstances, it ...

### Separation of a delayed mixtures of signals

I have three emitters in three different positions that emite three signals $S_1(t), S_2(t), S_3(t)$ with $$S_1(t)=S_2(t)=S_3(t)$$ Two receivers recive $R_1(t), R_2(t)$ with \begin{align} R_1(t)&=...

### Separating/recovering base signal from two mixed signals, given phase information

I have collected two signals, $B_1(x)$ and $B_2(x)$. The signals start and end at the same $x$-values. Each signal $B_i(x)$ contains: a base signal $b(x)$, which is the same for both, and a signal, ...
