What is meant by 20 dB signal-to-noise ratio?
I'm reading a paper in which a discrete signal
$$x(n) = s(n) + w(n)$$
is considered. $s(n)$ is a known, deterministic series, and $w(n)$ is white noise with zero mean. The authors write that

How to define SNR for multiple signals in noise?
I have to estimate the number of signals present in a measurement contaminated by additive noise given $n$-dimensional snapshot vectors $\bf x$, modeled as $ \bf x = \bf A \bf s + \bf z $ where $\bf ...

How to find quantization noise in my simulation?
For college we have to make simple exercise in simulink (matlab). (since my professor is not familiar with simulink, he can't help).
The question itself is, how can I simulate the SNR when uniform ...

How can you tell whether there's a signal (when your signal looks a lot like noise)?
This is my snoring detector again.
I've gotten pretty good at detecting a signal when there's anything there -- can track from a wall-peeling snore down to breathing you can't even hear in the ...

How to estimate the signal-to-noise ratio of a waveform?
I have a signal: $f_i(t_i=i\Delta t)$, where $i = 0\ldots n-1$.
The signal seems to vary quickly around a slower varying "trend". I am assuming that the quickly varying part is noise and the slowly ...

What are the various definitions for SNR, and their associated methods for measuring it?
The definition of SNR seems to be somewhat of a tower of babel in industry. What definitions of SNR are there (feel free to site application), and how exactly can it be measured for that applications?
