I have a difference equation for a Single Pole Infinite Impulse Response Filter, defined on a discrete time-series:
While the s brackets refer to a position n within the series. I'm looking for a visual way to represent this in order to get how this equation behaves. I have tried wolfram-alpha, MalLab... Is anyone me a pointer how I can make MatLab (e.g.) show me the plot for this function? Use-case is a DC offset filter, that uses this SPIIR filter with $\alpha=0,0004$. So it's mostly DSP related.
