Abstract
Digital fine delay processing provides an accurate and continuous delay for an analog signal generated from source digital data. A digital processor generates processed digital data corresponding to a delayed analog signal having a desired delay relative to the analog signal represented by the source digital data. The processed digital data is directly derived from the source digital data by digital processing, and both digital data are processed by a reference clock, or by the same phase and cycle of the reference clock. The processed digital data is converted into a the delayed analog signal. Modifying coefficients in a convolution function performed by the digital processor changes the desired delay so that the delay is accurately controlled and is continuous. Since the entire process is digital, degradation of the delayed analog signal is minimal.
