A Nonlinear Transfer Function Based Receiver for Wideband Interference Suppression

Figure 9

Zig-zag transfer function (grey) for an interferer with envelope amplitude of . By limiting to zero, the zig-zag function has an infinite slope in the zero-transition region 2. The creation of the zig-zag transfer function can be considered as shifting the linear transfer (black) in -axis in opposite directions in regions 1 and 3.
