SG, SGI – Signal generators

Block SymbolsLicensing group: STANDARD

Function Description
The SG and SGI blocks generate periodic signals of chosen type (isig parameter): sine wave, square, sawtooth and white noise with uniform distribution. The amplitude and frequency of the output signal y are given by the amp and freq parameter respectively. The output y can have a phase shift of $phase \in (0, 2 π)$ in the deterministic signals ( $isig \in \{1, 2, 3\}$ ).

The SGI block allows synchronization of multiple generators using the RUN and SYN inputs. The RUN parameter must be set to on to enable the generator, the SYN input synchronizes the generators during the output signal generation.

Inputs

RUN	Enable execution, run the binary sequence generation	Bool
SYN	Synchronization signal	Bool

Output

y	Analog output of the block	Double (F64)
