Few weeks ago Dialog Semiconductor announced a new series of FPGAs named as ForgeFPGA. The highlight of these new devices are not a high processing power, the highest speed or the big they are, the main highlights of these devices…
When I am working in a design for an FPGA, which involves the acquisition of any signal, I usually have to design a filter before using that signal in the control loop, or a protection. If the use of this…
If I say “software for engineering”, most of you probably think of MATLAB. I don’t know if there is any field in engineering which does not have a package in MATLAB, and digital signal processing and FPGA design are certainly…
Many times, in our designs we find a signal that our interest band of frequency is very close to the band that we need to reject. In this cases, in general, the most efficient way to attenuate the unwanted signal…
FPGAs have been present in the telecommunications field for many years, almost since they were created. On the other side, there are fields where FPGAs have not arrived yet for several reasons such as power consumption or price. But there…
In the previous post I have design an audio equalizer. On that design I have used 3 different FIR filters to split 3 different frequency bands in order to send them to different speakers. Very low frequencies will be sent…
Digital signal processing can be used in almost all engineering field, from seismology, to obtain the distance where an earthquake has been generated, to data science, but these areas use digital signal processing as a way to obtain the real…
Digital signal processing algorithms are, in general, purely mathematical algorithms that works perfectly on our notebook or MATLAB, but in real design, the algorithm starts to return us some unexpected results. One example of that is the quantification error. While…
In this blog we have seen how to develop a FIR filter. In this post you have an example of FIR filter where the coefficients are configured though AXI4-Lite interface. The goal of that post was the implementation of a…
Filtering is likely the most common DSP algorithm that any embedded engineer has to design, no matter it they are developing for an STM32, or TI DSP or, of course, en FPGA. Filtering is such important because the majority of…
