Convention Paper

An Almost Locked Oscillator for Electronic Music Synthesis

Authors: Simes, James G.

AES Convention 54 · Paper 1101 · May 1976

Abstract

This paper considers an oscillator which tracks a frequency within some predetermined error. This oscillator has the advantages of a phase locked or frequency division system in that the ratio of input to output frequency remains fixed. However, the output does not remain in time phase with the input but rather drifts in and out of phase. The almost locked oscillator uses two binary counters, a memory register, and a high frequency oscillator. the amount of tracking error is determined by the ratio of the input frequency to the internal high frequency oscillator. The system is an open loop system and therefore is able to track the input cycle by cycle.
