amplitude 

Returns the current amplitude value. 

dcOffset 

Returns the current Dc offset value. 

evaluate

frequency 

Returns the current frequency value. 

phase 

Returns the current phase value. 

setAmplitude 

Sets a new amplitude value.
 

setDcOffset 

Sets a new Dc offset value.
 

setFrequency 

Sets a new frequency value.
 

setPhase 

Sets a new phase value.
