The value of windowtype, when not passed as a list, should be the name or string, with or without the Window suffix, that corresponds to the windowing command. For example, to use a Hamming window, you can pass Hamming or "HammingWindow". In both cases, the command SignalProcessing[HammingWindow] will be used internally. Similarly, you can pass ["Exponential",0.5] or [ExponentialWindow,0.5] to use SignalProcessing[ExponentialWindow] with parameter value 0.5.

Denote $n=\mathrm{size}$ and $r=\mathrm{samplerate}$. For a given windowtype, the windowing Vector $W$ is the Vector of size $n$ formed by applying the window to the Vector of size $n$ filled with ones. Applying the window to any real-valued Vector $X$ of size $n$ is equivalent to multiplying $X$ element-wise by $W$.

Define $\mathrm{\rho }$ to be the Root Mean Square (RMS) of $W$, and $\mathrm{\mu }$ to be the mean of $W$. The Equivalent Noise Bandwidth (ENBW) is given by:

The SignalProcessing[EquivalentNoiseBandwidth] command is thread-safe as of Maple 2021.

$\mathrm{with}\left(\mathrm{SignalProcessing}\right)\:$

The SignalProcessing[EquivalentNoiseBandwidth] command was introduced in Maple 2021.
