The 3D Load Calculator is a tool where you can insert all the pieces you want to load in a container and see the optimal way to load it in a container. Each RC smoothing stage is a low-pass filter with a cut-off frequency of: f = 1 / (2 pi R C) Of course, the only frequency we really want to pass is 0Hz or DC, so we just make the cut-off frequency as low as possible, often below 1HZ. This calculator can handle large numbers, with any number of digits, as long as they are integers. 7 and self oscillates fine for almost any res above 1. Transfer function of II-order lowpass filter with two poles at is (6) The equivalent noise bandwidth of II-order lowpass filter, substituting Eq- in Eq-, is given by (7) Wolfram calculator for evaluating the integral. So, if we evaluate H(z) at z = pi/2 = 90 degrees, we get an idea of what the filter is going to do to signals at that frequency. In the case of L-section filter, one inductor and capacitor were present so if some AC ripples say 1% is left after filtering that can be removed in Pi-filter. 00 + shipping.
