@erabrar11 @grok This time-bandwidth product being large is important. Their magnitude spectra are similar in this ideal case only, while phase spectra are always different.

@WirelessPi @grok explain

An interesting question for junior DSP engineers. How can two different signals, a sinc pulse and an LFM pulse, have an identical spectrum? Best to figure it out yourself first, then see the answer in the link below. wirelesspi.com/the-fourier-do… #dsp #signalprocessing #Wireless

@BeadeNico Sure. Send me an email. wirelesspi.com/contact/

@WirelessPi Hi, Qasim! Is it possible the free download is not available anymore? May I have the pdf? It looks great!

After years of writing on DSP, wireless comms & SDRs, I’ve compiled my most popular articles into a book: Signal Processing Recipes for Communication Systems. 🧠 Free download: wirelesspi.com/dsp-recipes 📗 Full-color paperback: amzn.to/427YMbK Hope it helps your journey!

@Benathon Exactly. The magnitude plots are identical in the limit time-bandwidth product goes to infinity, but missing phase plots is the correct answer.

@WirelessPi They aren’t identical. And phase is the answer. The FFT shown on the bottom is the abs(fft()) and phase differences are not able to be represented

@seanmcdonaldxyz Thank you

@WirelessPi trending on hacker news! great article. I keep wondering if you could transmit LLM tokens in something like "fourier-encoded" (sorta) end to end audio devices over FM.

When a new member arrives at the DSP club, this is what they find at the club gate: I/Q signals. Perhaps a secret plot to keep most people out of the party? wirelesspi.com/two-birds-with… #dsp #Wireless

@minhhoanggia Thanks and yes, hopefully next year.

@WirelessPi Bought 3 years ago. Do you plan to have a new edition?

The wireless comms bundle (Wireless Communications eBook + 5G eBook + the SDR Course) is now available at a discounted price of $49 only. I hope that you will enjoy sending your own text and image in the air in GNU Radio experiments. learn.wirelesspi.com/5g-phy-ebook-s… #SIGNALS #wireless

What are the roadblocks in making a machine with human-level intelligence? In this article, I present a balanced view of the most important technology of our time. #AI #ArtificialIntelligence wirelesspi.com/ai-an-advanced…

This article illustrates how a simple operation on paper like taking a derivative is computed through discrete-time techniques and serves as a flavor for what DSP is like. wirelesspi.com/design-of-a-di… #DSP #Maths

@sevthreetr A comprehensive IQ tutorial, actually from 0 to 1, is in my pipeline. But explaining it in a tweet, never thought about that but excellent idea. This will be in the back of my mind when I'm writing that article! Thanks

@WirelessPi Can you explain IQ in a tweet?

I wrote this article just for fun. But writing this gave me other ideas about IQ signals and Fourier Transform that can simplify the whole concept for DSP beginners. Stay tuned. wirelesspi.com/rabbits-foxes-… #DSP #Signals
