Cannot import function freqresp from DSP.jl

[Grant.H]

Hi all,

Recently I met a problem that I cannot import function freqresp even after using DSP, while I can use other functions, such as PolynomialRatio. Does anybody know how this problem come? Thanks!

Works for me:

julia> Pkg.status()
      Status `/tmp/jl_rt9Iuj/Project.toml`
  [717857b8] DSP v0.7.6

julia> import DSP: freqresp

julia> freqresp
freqresp (generic function with 3 methods)

julia> freqresp(::String) = "yes!"
freqresp (generic function with 4 methods)

julia> freqresp("Does importing work?")
"yes!"

What exactly are you doing and what's the failure you are seeing?

This is the code that I have when importing the function. I am trying to generate a filter (using PolynomialRatio) and calculate its frequency response with freqresp.

(MyProject) pkg> status

I just realized that freqresp is not in DSP v0.6. Sorry about the disturbance, and thanks for your help. I will close this issue.
