Synethesised

1) Monophonic 

2) Additive

3) Polyphonic 

4) Subtractive 

5) Oscillator 

6) Filter 

7) Amplifier 

An elctronic sounf generating device. It is capable of crating synthetic sounds and can also manipulate synthetic sounds.

They come in and Analoug or Digital version. 

LPF = ( low frequencie pass) All frequencies below cut off can pass through 

HPF ( high frequencie pass) = All frequencies abouve cut off can pass through 

Band Pass Filter = Combination of LPF and HPF all frequencies not affected by either pass through 

Notch Filter = Used to cut spesific frequencies exteme band pass

Shelving Filter = Tone Control on hifis and guitar amps

Attack          Low                    Voltage
