Figure 5From: Analysis and Properties of Time-Varying Modified DFT Filter BanksExamples of ideal prototype filter and its deduced prototype filter coefficients h(n) at different roll-off factor r. (a) with r = 0.3 (b) with r = 0.5 (c) h(n) with N = 2M, r = 0.3, w(n) = 1 (d) h(n) with N = 2M, r = 0.5, w(n) = 1Back to article page
