Is that what a sdrplay RSP-DX is doing when you select decimation numbers Ie 2 - 4- 6 ect. Instead of bandwidth selection. I see it doubles what you see on the waterfall . What about zero if and low if . Can you go into more details about what it does and the results of it good or bad. I love your videos straight to the point and informative . Been a ham over 40 years but this is my foggiest subject. Thanks for giving us the meat and potatoes of RF details. AA4CP Chuck Port Salerno FL USA
yes decimation is downsample to reduce sample rate, the lower the sample rate, the lower the noise floor. so for weak signals want to set the decimation to max value. 73s take care, and thanks again for watching the videos. please give ideas for what videos you like to see, or topics you would like to see covered. thanks again.
hi sometimes we have a rf signal that it's not repeatitive like a sound wave how can we downconvert this signals to sampling with low sample rate analog to digital converters? is there any way?
Very helpful tutorial
Clicked on this video for the information but stayed for Dr moonshine 😆
Hilarious and informative !
Nice presentation. Wish my lecturer is as funny (and as clear) as you!
please let me know any topics you like covered.
Funny and conceptually easy to understand presentation Sir. Can you please make a video on DUC..?

PS I agree loop antennas kick ass and it is ALL ABOUT THE SNR !

Thank you. Where can I get a breakout board with one of those 125 mhz ADCs on it that I can hang off my ESP32 ?
I just have the 125-14 red pitaya board
Can you explain the last slide? I don't understand where this information comes from. Do you have any extra resources so I can read up on it?
pavel demin red pitaya notes just google that
Extra credit for Rush Limbaugh!
AAAAAAAAAAAAAAAAA I FINALLY GET IT AAAAAAAAAAAAAAAAA
good
Pavel Demin maybe?

A mixer to shift the rf signals to af signals
"Red papaya" hahaha!
Where can the source code for the DDC be found?
Pavel demin , google that.
