The effect of limited-precision weights on the capacity of the threshold Adaline is examined. In particular, an experimental technique is used to determine the capacity of the threshold Adaline for several different levels of weight precision. The results provide some insight into the manner in which the capacity of the threshold Adaline increases as the number of bits per weight increases. As might be expected, the growth in capacity due to an additional bit per weight is greatest when the original number of bits per weight is small, and decreases as the original number of bits per weight increases.
