…oat}} There is an upcoming package for FFTs on generic number types https://github.com/JuliaApproximation/GenericFFT.jl. This will enable, in particular, convolutions with `BigFloat` and `Complex{BigFloat}` arrays. To make this Just WorkTM, we...
Bumps [julia-actions/julia-runtest](https://github.com/julia-actions/julia-runtest) from 1.7 to 1.8. Release notes Sourced from julia-actions/julia-runtest's releases. v1.8.0: Add test failure annotations on v1.8+ What's Changed Make required checks work by @SaschaMann in julia-actions/julia-runtest#53 Fix...
As I'm writing up things that use this package, it occurs to me that it would be nice to cite it in some way. Maybe we should think about how...
Hi. I am taking a course in university aboud DSP and I wanted a plot of a filter that looks like the "zplane" plot in MATLAB. I could not find...
This is a proposal for fixing analog filter design (see bug #341). For this frequency normalization has been shifted to function `digitalfilter()`. And function `analogfilter()` doesn't require any sampling frequency...
This pull request allows to create ComplexBandpass filters for one sided pass bands (different pass bands for positive or negative frequencies) I haven't implemented `scalefactor(coefs::Vector, ftype::ComplexBandpass)` yet, as I'm not...
I am having troubles setting up the stateful FIRFilter with the information given in the docs. How can I properly construct a FIRFilter from a designed filter using e.g. Lowpass...
This is on Julia 1.1 and DSP 0.6.0: ``` julia> @code_warntype resample(randn(100), 1//5) Body::Any 1 ─ %1 = DSP.Filters.resample_filter::Core.Compiler.Const(DSP.Filters.resample_filter, false) │ %2 = invoke %1(_3::Rational{Int64}, 1.0::Float64, 60::Int64)::Array{Float64,1} │ %3 =...
I'm trying to use `DSP.conv` to do some simple image filtering on a grayscale image, but it seems like the datatype is not supported: ``` jl using TestImages using ImageView...
I have an application where I would like to be able to control the padding for the convolution. The way I am doing this now is to just use a...
