Abstract
An interpolation circuit () generates a plurality of intermediate amplitude values linearly related to two consecutive signal amplitude values using a system of adders and memory elements. A first stage () of the interpolation circuit calculates a one-half amplitude value; a second stage () calculates one-fourth and three-fourths amplitude values, and a third stage () calculates one-eighth, three-eighths, five-eighths, and seven-eighths amplitude values. A comparator () receives a threshold value () and compares each of the intermediate amplitude values to the threshold value. A decoder () generates a time of arrival adjustment value that is subtracted from a low resolution time of arrival to generate a high resolution time of arrival.
