-- The wpfb unit can handle a wideband factor > 1 (g_wpfb.wb_factor) or
-- a narrowband factor > 1 (g_wpfb.nof_chan). Both factors can NOT be

-- . For wb_factor = 1 the wpfb_unit uses fft_r2_pipe and supports nof_chan >= 0
-- . For wb_factor = 1 the wpfb_unit uses fft_r2_pipe
-- . For wb_factor > 1 the wpfb_unit uses fft_r2_wide
-- . For wb_factor = 1 the wpfb_unit supports nof_chan >= 0
-- . For wb_factor > 1 the wpfb_unit only supports nof_chan = 0, because the

-- . For wb_factor >= 1 the wpfb_unit supports nof_chan >= 0, even though the
-- concept of channels is typically not useful when wb_factor > 1.
