What is the "bilinear interpolation kernel" in personlab paper?
When I read «bilinear interpolation kernel» in image processing, I assume that they mean bilinear image imterpolation:
y(n+t) = (t-1)x(n) + tx(n+1)

If you decide upon a fixed uniform upsampling factor and standard dsp «zero-fill then lowpass filter» upsampling, the convolution kernel turns out to be samples of a triangular waveform.
