Asia 25

The term ASIA element (an acronym for analog signal memory with intrinsic adjustment) denotes a motif for biological information processing structures that is based on leaky integration of an input signal.

Thus, an ASIA element performs the following tasks:

  • Retaining the information with given time constants.
  • Automatic extinction of obsolete signals.
  • Linear dependence of the system`s response from input signals to prevent distortion effects.
