ABSTRACT:
This invention synthesizes a continuous wave signal from a finite periodic complex signal waveform by digitizing the finite waveform, matching the phase of the digitized waveform at its recorded beginning (head) to its recorded end (tail) and then playing out the waveform over and over in a head-to-tail fashion. The quality of the "phase match" between the waveform head and tail as well as the head-to-tail segment length determines the frequency accuracy of the synthesized continuous waveform. The basic formula ##EQU1## is used.
