Rectangular window

boxcar(n)

Returns

rectangular window, returned as a vector.

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.

Examples

b <- boxcar(64)
plot (b, type = "l", xlab = "Samples", ylab =" Amplitude")
