Web7 aug. 2024 · It's quite easy to do low pass filtering on discrete data with equally spaced frames (like from your camera). You could choose a = 0.1, then you have some data, eg. [1, 2, 3]. Let's use an initial value of y0 = x0 = 1. Then your filter values will be y1 = 0.1 * x0 + 0.9 *y0 = 1, y2 = 0.1 * x1 + 0.9 * y1 = 0.2 + 0.9 = 1.1, y2 = 0.3 + 0.99 = 1.29. Web9 apr. 2024 · You can use a relation Hhp(ejω) = 1 − Hlp(ejω) in time-domain, so that hhp[n] = δ[n] − hlp[n] = δ[n] − sin(ωc(n − α) π(n − α), in order to have the same cut-off frequency for the both filters.

Analog filters consist of imperfect electronic components, whose values are specified to a limit tolerance (e.g. resistor values often have a tolerance of ±5%) and which may also change with temperature and drift with time. As the order of an analog filter increases, and thus its component count, the effect of variable component errors is greatly magnified.
