When the low-pass filter decimates, does it decimate before or after filtering?

Went through this whole series, it was great! The only thing else I'd like to see is at the very end when you create the entire system is show how you could use it to send a data stream like text or something.

Great explanation of Interpolation in the Repeat block, which was not intuitive. Great that Jason pays attention and explains such details. That's what makes these lessons so great.

Got a question @26min: how can you show a complex signal in Im and Re part as 2 separate signal while only 1 output from the source block? does this mean actually there are 2 signals to achieve complex signal?

Big Aha moment on negative frequencies. I now understand clearly the connection with the Zero IF thing shifting the signal around 0 Hz before sampling by the Analog Digital Converter. The key element to understand is the parity of the cosine and sine functions : cos (x) = cos (-x), and it is therefore not possible to differentiate between a frequency above and below carrier frequency (both positives because real frequencies) in the baseband range, that will turn into a positive and negative frequency (respectively) once shifted and centered around 0 Hz. When applying the cosine function alone to these frequencies, because of the parity of the function, we lose a piece of information about the sign of the frequency, that tells whether it is a few Hertz above or below carrier frequency. The quadrature signal (sine) stores the other half of the information that enables to differentiate lower range frequencies from higher range frequencies, and therefore reconstruct the real signal frequency. Thanks a bunch !

fft size 100 i get this error: Assertion "not (fftsize & (fftsize -1))#The FFT Size should be a power of 2" failed.
@preuton6 ай бұрын
I was confused with the analogue way. For example de IF of FM is 10.7Mhz. With SDR there is no IF but the sidebands are direct available after mixing. Is this correct?
@miltonriosj.13204 ай бұрын
Let's say that with SDR there is IF but it is zero and of course appears a negative frequency another way to get this is that the IF is shifted to zero intead of 10.7Mhz, this is so, to make easier to the processing algorithms to do the demodulation process.

Hi Prof Jason thank you again for the lessons , sorry for this question , but i don't understand why do we use the keep in N bloc , In my opinion we are throwing good samples that were behaving themselves .

@anthony36046 ай бұрын
I dont get something , you say " We are going to throwing out samples that are not in the central region " but from my understanding the decimation happens after the filtration so you are throwing mainly samples of the central region. And therefore the aim of the decimation is just to reduce the sample rate to reduce computation time at the cost of quality . Or did i miss something ?

Wonderful, thanks. 45 Years ago in 'my' school (when we didn't have these software tools to visualize everything) - it was a lot harder to grasp what is really happening from just the math. You did a great job with the step, by step visualization. :-)

Why, at @20:27 in the demonstration of the Interpolating FIR Filter, did you bypass the throttle block by connecting directly to the signal source when during the other demonstrations you used the throttle block?
@stevehageman67857 ай бұрын
Thanks for the tutorial - I have programmed my SDR's in C# and Python, but this tutorial really shortened the learning curve on getting going with GNU Radio. I used this tutorial with my ADALM Pluto with very few changes - running the latest version (Feb 2024) RadioConda on Windows 10. Works great! You have nothing to be sorry for - your 'Live Coding Demo' went better than 99% of the live coding demos that I have done! As we say in R&D: "What could go wrong?" Ha, ha, ha, ha...... ;-)

Thank you for all SDR videos. Is there any reason you switched to RTL SDR for this section? Can I use Pluto as well? Is it because the sensitivity, noise figure or other spects of those?
@abdallahableel43735 ай бұрын
You can use pluto, just replace the TCXO with a proper external 1 pps or < 1 ppm source, set it at 40 MHz and plug it to u.fl ext_clk port, and re define uboot variables in linux environment of Pluto.

Thank you. I always wondered how gas tube lasers worked. I understand the basics of diode lasers but have no familiarity with gas lasers. I guess the next thing I should research is the definition of "mode" in this context, because I'm a layman, with no experience except researching the basics for the two types of lasers I'm using at home: direct diode and diode pumped solid state. Dye lasers are also a mystery to me. It is only the inexpensive lasers I can tinker with, and I haven't really looked into the definition of "mode" because, as far as I'm aware (I could be wrong, admittedly. You're the expert, not me 😊) direct diode lasers are single mode, so I've only really seen the term "mode" mentioned in passing.

The camera is mirrored , so he writes like normal which would be mirrored for those who look at the board but if you look at it through a camera it reverses it so it's the right way
