Thank you! Video useful way beyond STM32 programming. But embedded implementation is also excellent for education. Good that you always divide theory and practice!
I found your TH-cam channel pretty recently and it seems I found a golden gem!😁 Love your HW design videos with advanced tips and tricks and videos about STM32 HW/SW. Keep up the good work please 😃
Thanks, another clear video that will serve as a go-to refetence for years to come. One (dumb) question though - under what circumstances would you choose to sample higher, then perform decimation filtering? Why not just sample at the post-decimation rate initially?
Phil, great content. I've very much enjoyed your filtering information! In terms of down-sampling, what are your thoughts on averaging M samples rather than simply skipping M-1 samples? I have a lot of data systems that sample at 1KHz, but then output at 10, 100 or perhaps 250 Hz. Most of them are implemented very much like this video, with the exception that we average M samples of the filtered data to create the output. Is there a good reason to not do that?
Hi Phil, Thanks for creating these wonderful tutorial videos on DSP! I really love them. Do you have any recommendations on books/study materials which cover both theoretical and practical aspects of DSP? I have got some ARM uC boards on which I would like to implement these filters/algorithms.
Very nice, I would like to download the firmware for this project as well as the others. It is not included yet in the github repository. It is still an older version.
I see on the little brain board you use a 6 pin pogo connector, I have only found those connectors for around £100 from the USA, do you know of any cheaper alternatives?
The idea behind decimation is that after filtering the signal is smooth, so there is no point of keeping all output samples - they bear no information.
Ugh! Your video & explanation was really great but C# is such a horrific bastardized programming language of the lowest level from the worst ever software company!
Man your work has just no comparison, amazing as always, thanks for all your hard work!
Thank you very much! Very glad that you are liking the videos :)
Thank you Phil for the best micro-controller content on TH-cam. Congratulations on reaching 50K.
Thank you so much, Isaac!

Than you, Marek - glad you found the channel, many more videos to come :)
Thank you Phil, this is the best explanation I ever found on the decimation filter. Could please you also make an video on CIC decimation filter? :))
Amazing as always, can't wait for more :D
Thank you, Kamil!
Awesome as always! Thank you :D
Thank you!

Thanks for watching :)
Excellent work，I learned a lot，thank you very much！
Thanks!

Why are the samples thrown away? What happens if you take the average of M samples from the FIR filter as the output for the decimator?
Hi Phil, Thanks for creating these wonderful tutorial videos on DSP! I really love them.
Do you have any recommendations on books/study materials which cover both theoretical and practical aspects of DSP?
I have got some ARM uC boards on which I would like to implement these filters/algorithms.
Thank you! The main book I’d recommend is ‘The Scientist and Engineer’s Guide to DSP’ by S. Smith.

Thank you very much!
I see on the little brain board you use a 6 pin pogo connector, I have only found those connectors for around £100 from the USA, do you know of any cheaper alternatives?
I'm afraid they are quite pricey. I haven't come across any cheaper alternatives so far.
WOW! Very cool.
Thanks, Stephen!
Hi Thankyou for your videos.could u please make a turorial on interfacing stm32 with any of the 13.56 mHz rfid chip??
I love your videos! Very heavy going for me unfamiliar with stm32Cube but nice. Question though, can't you just set the ADC to a lower sample rate?
You can benefit by sampling at a higher rate and then filtering and decimating, this helps you improve resolution by oversampling.
The idea behind decimation is that after filtering the signal is smooth, so there is no point of keeping all output samples - they bear no information.
Hi, really nice work and impressive as always.
I have a request can u make a video on how one can implement PID controller ?
Thank you! I have a PID controller video on my channel :)
Thanks !
Thanks for watching!
can you explane the CIC filters
Will you resume KiCAD related videos?
Yes, I will!
Last time I talked to altium the quoting me many thousands of dollars for a license - I am a one man design firm so that's quite steep...
Ugh! Your video & explanation was really great but C# is such a horrific bastardized programming language of the lowest level from the worst ever software company!
