Impedance mismatch

Definition

Impedance mismatch refers to the disparity in electrical characteristics between two components or systems that can hinder their ability to effectively communicate or function together. In the context of hybrid neuromorphic-conventional computing systems, this mismatch can occur due to differences in data representation, processing speeds, and energy efficiency, which can impact the overall performance and integration of these systems.
