QUESTION
is there a way to have an alternative implementation of lfilter within scipy? I want to use the cusignal library and lfilter is not supported at the moment.
Here's my my current code that I want to speed up:
...ANSWER
Answered 2020-Oct-29 at 05:30Even though your filter is in principle an infinite impulse response (IIR) filter, the impulse response for this particular filter decays very fast. You can compute the impulse response by running an impulse through it with lfilter like lfilter(b, a, [1] + [0]*99)
. Here is what I get:
As you can see, the taps are nearly zero above sample 20 or so. So you can take the first 20 samples of the impulse response to make an accurate truncated FIR approximation. From there, you can apply that FIR approximation with any FIR filtering function, like np.convolve, scipy.signal.convolve, or scipy.signal.fftconvolve.
Another thought: With any of these filtering functions, you could try casting all the args to np.float32. They might internally switch to a 32-bit float implementation that is faster than the 64-bit float implementation.

Install cusignal
cuSignal has been tested on and supports all modern GPUs - from Maxwell to Ampere. While Anaconda is the preferred installation mechanism for cuSignal, developers and Jetson users should follow the source build instructions below; there isn't presently a conda aarch64 package for cuSignal.
