SF_Sine_Generator

Sonic Flow Blocks Reference Guide

The purpose of SF_Sine_Generator is to generate a sine signal of desired frequency and amplitude.

SF_Sine_Generator (const char* name = 0);

This is the constructor of a SF_Sine_Generator block. Following attributes of the class are specified in the constructor:

• SF_Sine_Generator
  • class name: "Sine generator"
  • producer: yes
  • consumer: no
• List of input terminals
  • inputs[F]
    • input name: "freq"
    • multiple connections: no
  • inputs[AMP]
    • input name: "amp"
    • multiple connections: no
    • default value: 1
• List of output terminals
  • outputs[Y]
    • output name: "y"

virtual ~SF_Sine_Generator ();

This is the destructor.

virtual void finish ();

virtual void initialize ();

virtual void execute ();

The initialize - execute - finish chain of function calls is used to carry out the simulation of a block. See SF_Block.

The initialize does nothing specific.

The execute carries out the actual simulation process. Sine signal of given frequency (F signal) is generated and it is amplified pointwise with the A signal.

The finish does nothing.

enum Input_Indices {F, A};

enum Output_Indices {Y};
