Welcome to the dspfpgatools blog. In this blog I hope to create free online calculators/tools that could come in useful for Engineering, in particular for Digital Signal Processing and Digital Hardware Design.

You can navigate through this blog using a variety of means, including using the drop down menus just below the header.

So far the following tools have been implemented:-

1. FFT Calculator - this can be found here.
2. Power Spectral Density (PSD) estimator - this can be found here.
3. FIR Filter Frequency Response calculator here.
4. Decimal (floating point) to binary converter and VHDL productivity tool here
5. VHDL Entity to Component Instantiation Converter here
6. VHDL Entity to testbench template generator here

I will not claim responsibility for the accuracy or correctness of the results - use the online tools at your own risk.
