Analog signal processing is any signal processing conducted on analog signals by analog means. Specifically the mathematical algorithm that processes the signal is implemented with analog electronics in which the mathematical values are represented as a continuous physical quantity, an analog, usually as a voltage, electric current, or electric charge around some components in the electronic devices. A small error or noise affecting such physical quantities will result in a corresponding error in the signals represented by such physical quantites.
