Impulse responses (IPR) of the singular window functions and dual-/tri-apodization. Impulse responses (IPR) of (a) rectangular window function (R.W), (b) Dolph-Chebyshev window function (D-C.W), (c) Kaiser window function (K.W), (d) dual-apodization (D.A) using rectangular and Dolph-Chebyshev window functions, and (e) tri-apodization (T.A) using rectangular, Dolph-Chebyshev, and Kaiser window functions. Bin is a spectrum sample.
