The axolotl (Ambystoma mexicanum) has extraordinary regenerative abilities—the salamander can regrow lost limbs and repair ...

The answer lies in an extremely clever circuit: the regenerative detector. A small amount of positive feedback is applied to an amplifier that has a tuned circuit in its path, and the effect is ...

The principle of a regenerative receiver is that it takes a tuned radio frequency receiver with a wide bandwidth and poor performance, and applies feedback to the point at which the circuit is ...
