Abstract
In a character recognition system, an improved adaptive information signal discriminator for detecting an information signal when it varies over a wide range and/or when the background noise varies over a wide range. The discriminator is able to adaptively follow the widely varying background noise level by averaging the response time of the discriminator. The discrimination of a widely varying information signal is had by summing a portion of the information signal with the supra background averaged level. The discrimination may be repeated to develop the required sensitivities as required to accurately process the data.
