WebDec 27, 2024 · It may take a little more work, but you could change the forward FFT so that it takes its input directly from the real-valued input vector. This is probably close to twice as fast as the complex FFT you are currently doing (but this is just for the forward FFT, so your overall speed increase might be up to 25%). grand design reflection 297rsts 2021

WebDec 22, 2024 · For speed, you definitely want to reuse FFTW plans if possible. When reusing a plan across multiple calls to hilbert, remove the fftw_destroy_plan (plan) line within hilbert, otherwise the plan won't be valid to use in the next call. Instead, destroy the plan at the end of the program. Edit: I had missed previously that you use two plans, one ... WebJul 13, 2024 · What appears to be broken is that my code drawing the second half of a 2-bit 2-dimensional Hilbert Curve backwards.

WebInstead, bandpass is usually done by cascading a HP and a LP filter, and bandstop is the mixed output of a HP and a LP filter. However, there's bandpass biquad code (for example RBJ biquad filters). Cheers Peter.
