In summary, the conversation is about implementing a feedback system on a DSP using an LTI transfer function to stabilize a dc-dc converter. The problem is converting the digital transfer function into code, but the conversation suggests that it should not be too difficult if a difference equation is used. The person speaking is confident in their ability to figure it out.

Helo,
I am currebtly working on a dsp, in a goal to implement a feedback system in the form of an LTI tranfer function that will stabilize a dc-dc converter.
The problem is as follows:
We have the digital desired transfer function, and the problem is how to work with the dsp for impelmentaion on the dsp.
We are lookng for materail on line that will help us do that.
our dsp is:TMs320F28x.
Thx

Is your problem related to your specific DSP, or how to convert your digital transfer function into code?

how to convert the digital transfer function into code.
this is the problem.
exactly!

If you can convert the transfer function into a difference equation, this should be pretty easy. If you need help, can you provide us with the transfer function?

thanks kerry
i understand what you are saying...this is not tough to implement on the DSP i can figure it out for myself

cheers:)
 

1. What is DSP implementation of LTI transfer function on TMs320F28x?

DSP (Digital Signal Processing) implementation of LTI (Linear Time-Invariant) transfer function on TMs320F28x refers to the process of using a digital signal processor to implement a system with a transfer function that is linear and does not vary with time. The TMs320F28x is a specific digital signal processor that is commonly used for this purpose.

2. Why is DSP implementation of LTI transfer function important?

DSP implementation of LTI transfer function is important because it allows for the efficient and accurate processing of digital signals. This is particularly useful in applications such as audio and video processing, communication systems, and control systems.

3. How does DSP implementation of LTI transfer function work?

DSP implementation of LTI transfer function involves converting an analog signal into a digital signal, applying the LTI transfer function to the digital signal, and then converting the resulting signal back into an analog signal. This is achieved through the use of digital signal processing algorithms and techniques.

4. What are the benefits of using TMs320F28x for DSP implementation of LTI transfer function?

The TMs320F28x is a high-performance digital signal processor that offers advanced features and capabilities for DSP implementation of LTI transfer function. Some of the benefits of using this processor include its fast processing speed, low power consumption, and a wide range of built-in peripherals and interfaces.

5. Are there any limitations to DSP implementation of LTI transfer function on TMs320F28x?

While the TMs320F28x is a powerful processor, it does have some limitations when it comes to DSP implementation of LTI transfer function. These limitations may include limited memory and processing resources, as well as a learning curve for users who are not familiar with digital signal processing.
