boxcar {gsignal} | R Documentation |
Rectangular window
Description
Return the filter coefficients of a boxcar (rectangular) window.
Usage
boxcar(n)
Arguments
n |
Window length, specified as a positive integer. |
Details
The rectangular window (sometimes known as the boxcar or Dirichlet window) is
the simplest window, equivalent to replacing all but n
values of a
data sequence by zeros, making it appear as though the waveform suddenly
turns on and off. Other windows are designed to moderate these sudden
changes, which reduces scalloping loss and improves dynamic range.
Value
rectangular window, returned as a vector.
