Abstract
A neural network binary code recognizer for decoding n-bit binary code words. This apparatus includes inputs for inputting n signals into the recognizer, each of the n signals representing a bit value of an n-bit binary code word, which may or may not be corrupted. The apparatus also includes n amplifiers, each having an input for receiving a respective input signal. The amplifiers condition the respective input signals to generate respective output signals at one or more bit values of one or more corresponding predetermined valid n-bit binary code words. The apparatus further includes a device for approximating an image product for each of the one or more predetermined valid n-bit binary code words, each approximated image product comprising the product of an output signal from each amplifier in accordance with a respective predetermined valid n-bit binary coded word. Each approximated image product is fed back to an input of each amplifier in accordance with a bit value of one or more predetermined valid n-bit binary code words to enable an output signal of a respective amplifier to dynamically approach each bit value of the input n-bit binary code word.
