Abstract
The digital interpolator herein selectively provides linear interpolation between successive digital data words in a stream of such data words. The data words each contain a control bit together with first and second multi-bit fields with the control bit having a first or second level respectively designating whether or not interpolation is to take place through that data word. The first bit field contains differential data, representing the value between successive data words, only when the control bit is at a first level. The second bit field contains the interpolation interval to be effective when the control bit is at the second level. When no interpolation through the assigned data point is desired, the control bit is at the first level and the circuitry responds to provide an output signal having a digital value corresponding with a first data word to which there is added the differential data from the first bit field to obtain the next output signal. If interpolation is desired through the assigned data word, then the circuitry responds by repeatedly adding interpolation increment from the second field to the previous output signal for N iterations representing N interpolation increments.
