WebApr 10, 2024 · The Christensen Ridgeline FFT is the most expensive rifle on this list, but it costs half as much as Christensen’s most expensive model. The rifle I tested, chambered in 6.5 Creedmoor, delivered some three-shot groups as small as 0.20 inches — or a single ragged hole — and is one of the most accurate hunting rifles I’ve ever tested. Webused to unpack the FFT outputs to N-point complex values because the FFT outputs are N/2-point complex values. After unpacking, the 1024 complex values are used to compute the power values of FFT outputs [7]. Each power values is computed by the formula , where R is the real part and I is the imaginary part [6, 8].
