Saw
See Sawtooth Waveform.

Sawtooth Waveform
The name comes from the fact that the waveform resembles with the form of a sawtooth of a wood saw, it is slowly going up to then steeply fall down. The waveform is simple to achieve in electronics, commonly done by slowly charging and capacitor and then very fast short-cursuit it to let the voltage fall happend.

sin
Mathematical function, see Sine Waveform.

Sine Waveform
The Sine waveform is a waveform following the mathematical function of sin. To the ear will it sound like a very pure tone. Througth the Fourier theorem we can show that any repetive function can be fully explained as a set of sines of diffrent phase and amplitude.

Square Waveform
The square waveform has got it's name from the fact that it is similar to an square. It has two levels, they are equally long in time and they are alternated with very quick jumps (very steep slopes). Square wave can also be viewed as being an 50% PWM waveform.

Sustain
Sustain is a term used for envelopes. It is the level that the decay will strive for. One can speak of a sustain phase such that the envelope is very close to the sustain level and the decay changes are very small. The sustain phase will end when the trigger ends it. Normally can the sustain level be controled.

Sync
See Synchronisation.

Synchronisation
Often shorted to sync.

1. Synchronisation is when two normally independent events have been forced to occur in a ordered time structure. It is said that two events is in synchronisation when they follow an predecided time structure while they are said to be out of synchronisation when they do not follow and time structure. It is common for synchonisation to be as simple as to say that the events should happend at the same time or possibly with a fixed time delay.
2. The process or work needed to be done in order to get two or more events to apear to be synchronious.
3. In VCOs it refers to a synchronisation process in order to get the waveforms phase to be syncronised from some source.
