How to calulate a power of real-valued signal in watts?
Given a discrete real-valued signal with $N$ samples and $F_{s}$ as the sampling frequency. Asked to calculate the power of the signal in $\textrm{dB}_{\textrm{m}}$. … The power of a discrete signal with $N$ samples, as I know, is defined as:
$$
P = \frac{1}{N} \sum_{n = 1}^{N} \left( x \left[ n \right] \right)^{2}. \tag{2}
$$
Is this a correct formula? …
