computes equivalent noise bandwidth of a window
EquivalentNoiseBandwidth( size, windowtype, samplerate )
EquivalentNoiseBandwidth( windowvector, samplerate )
Positive integer for the size of the window.
(optional) Either a list, name, or string, specifies the windowing command to be applied. The default is "none" (for no windowing to be applied). If a list is passed, the first element provides the name of the windowing command, and any remaining terms are passed as options to the command.
1-D rtable or list of numeric values, specifies the Windowing Vector.
(optional) Positive numeric value for the sampling rate. The default is size or numelems(windowvector), depending on the calling sequence.
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=size and r=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 ρ to be the Root Mean Square (RMS) of W, and μ to be the mean of W. The Equivalent Noise Bandwidth (ENBW) is given by:
