9. Passive elements

The THAT comes with multiple passive elements, which require no supply voltage to fuction. The following passive elements can be found on a THAT:

  • Resistor network (XIR)

  • Capacitors

  • Diodes

9.1. Resistor network (XIR)

THAT XIR unit

THAT XIR electrical circuit

The XIR elements can be used to increase the number of inputs of an integrator or a summer by simply connecting the SJ panel of an integrator/summer with the SJ panel of a XIR element. The free XIR inputs now function as inputs for the corresponding computing element.

They can also be used to convert an inverter to a summer, again by connecting the SJ panels.

9.2. Capacitors

There are five free capacitors to be found on each THAT, three with 100 picofarad and two with 100 nanofarad.

9.3. Diodes

There are six free diodes on each THat, four standard diodes and two Z-diodes. Diodes can for example be used to generate stabilzed sinus functions.
