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. https://t.co/Nzo7WfpYvw #dsp #signalprocessing #Wireless

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? https://t.co/tW1qF6n97C #dsp #Wireless

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. https://t.co/9sAxhykcGX #DSP #Maths

Linear Frequency Modulated (LFM) waveform is less vulnerable to noise compared to the rectangular pulse. LFM also gives higher resolution.

Marilyn vos Savant, in her magazine column in 1990, answered a puzzle that bewildered the brightest of minds in the United States, including high profile mathematicians. This continues to be the case today. What exactly made this puzzle so unique? #puzzles https://t.co/diCE3aNDVw
