====== Supplies ======
The project Supply contains a couple of sub-projects which serve slightly different purposes:

  * [[.:supply:start|Supply]] -- This module is meant to provide symmetric supply for analog circuits. It turns symmetric unregulated voltage into fixed regulated +/- supply. E.g. +/- 18 V → +/- 15 V .
  * [[.:supplyzwei:start|SupplyZwei]] -- This module also provides a symmetric supply. But it contents itself with a single (but larger) voltage. A power amplifier is used to ‘invent’ an intermediate voltage level.
  * [[.:supplydrei:start|SupplyDrei]] -- This module represents yet another way to supply analog circuits. It quadruples and rectifies an unregulated AC voltage with a Delon circuit. Subsequently, two regulators provide a reasonably stable symmetric +/- supply.
  * [[.:dualpowersupply:start|DualPowerSupply]] -- Double Voltage linear power supply
