Description

The signal generator module repository contains SIN generator ramp generator, trapezoidal & profile- generator modules. The signal generator modules are implemented using modulo arithmetic counter (i.e. Any overflow is ignored and only the remainder is kept) to precisely control the frequency. The frequency of the generated signal is reciprocal of the time it takes for successive overflow of modulo counter, which in turn commensurate with the step value added to the counter. Thus by changing the step value, one can precisely control the frequency.

The step value is not directly commanded to vary the frequency, instead the modulation of frequency is performed using the normalized variable "freq" which is normalized to the maximum frequency. The maximum required frequency is predetermined based on the application requirement and it set by initializing the "step_max" input. Thus, the normalized variable "freq" allows the user to control the frequency of the signal between 0 to maximum frequency. This strategy is adopted for all signal generator modules. The following table summarizes the set of modules that are available in this library.

Note:

  • Documentation of Signal generator Modules is archived in the self-extracting zip file, and the pdf files can be found in c:\tidcs\c28\dsp_tbox\sgen\doc directory.

  • Software Test Bench (STB) support library must be downloaded to use the STB examples.
