This tutorial will describe how to convert between data types. The previous tutorial, Signal Data Types, presents an introduction to the Complex Float 32 and Float 32 data types for representing digitized signals.

Char/Byte Data Type

The Char or Byte data type is another useful data type for representing binary data. The Byte data type is represented by the magenta color in GRC:

Search for the Random Source block and drag it into the workspace:

The block defaults to the green Integer 32 data type. Double-click the block to open the properties and modify the data type to byte:

The Random Source is now converted to the magenta Char or Byte data type.

Converting Byte to Float 32

The default parameters of the Random Source will randomly generate values of 0 and 1. We will want to view them using the QT GUI Time Sink, add it and the Throttle block into the workspace and connect the blocks:

  • random source
  • use in modulator

char/byte data type convert to float display
