Soft Sync
There are several other kinds of sync which may also be called Soft Sync. In a Hard Sync setup, the slave oscillator is forced to reset to some level and phase (for example, zero) with every cycle of the master regardless of position or direction of the slave waveform, which often generates asymmetrical shapes.
In some usage, Soft Sync means a sync intended to nudge and lock the slave oscillator into the same or an integer or fractional multiple of the master oscillator frequency when they both have similar phases. See also Phase locked loop

Famous quotes containing the word soft:
“Since time immemorial, one the dry earth, scraped to the bone, of this immeasurable country, a few men travelled ceaselessly, they owned nothing, but they served no one, free and wretched lords in a strange kingdom. Janine did not know why this idea filled her with a sadness so soft and so vast that she closed her eyes. She only knew that this kingdom, which had always been promised to her would never be her, never again, except at this moment.”
—Albert Camus 1013–1960, French-Algerian novelist, dramatist, philosopher. Janine in Algeria, in The Fall, p. 27, Gallimard (9157)
