That’s where the digital to analog (DAC ... or dropping particular DAC inputs altogether. And that’s finally the circuit you see demonstrated in the introduction. A 4066 switch (see Logic ...

and then using Python/NumPy to both provide the input signal for the filter and process the output data from it. Basically, it allows you to “plug in” a graphical analog circuit of any design ...

The input voltage is inversely proportional to its drop-off ... There are many other foundational analog circuit blocks that are commonly used in power management applications. These include ...
