### Energy and Time Signals

In Signal Processing, we broadly categorize signals as either being "Energy Signals" or "Power Signals". If the total Energy for a signal is finite, we categorize it as a Energy ...

### Why the received SNR increases with bandwidth?

I am performing the following simulation: Complex chirp signal with bandwidth [-B, B] is transmitted through a multipath channel which has $N$ taps all being complex Gaussian variables (i.e., ...

### Random Signal Energy

Why the energy of random signal(random process) is infinite? and why random signal can not be zero at infinity? I know that there is a relation between the tow questions but I'am still confused.

### What does not happen if we limit the duration of this sequences to 2014 samples?

I am confused with this multiple-choice question: Assuming that $x(n) = e^{-2n}u(n)$, what does not happen if we limit the duration of this sequences to 2014 samples? A. The signal power leaks out ...

### How to extract noise from a signal in order to get both noise power and signal power

I have to implement a function to get an accurate SNR value. For that, I would need a separate noise signal to get the signal power and noise power but I have only one noisy signal (a .wav file.) ...

### Is this a valid way to calculate SNR?

If I calculate 1.) the average power of a signal, $P_s$, in terms of the average energy of the signal, $E_s$ and take it as a constant over a given period of time, $T_s$, as $P_s=E_s/T_s$ where $E_s$ ...

### Estimating the SNR of respiration signal

I'm trying to evaluate the SNR of a respiration signal on MATLAB environment, so the bandwidth considered is [0.04-1Hz]. The problem is that noise is overlapped on the signal, so I can't evaluate the ...

### Understanding SNR effect on signal [duplicate]

I'm studying how SNR is measured, I know is a ratio between the power of signal and noise, and is given in a logarithmic scale but I'm confused about how is interpreted, for example does a SNR of 6 ...
