Delay estimation using cross correlation
Started by 4 months ago●6 replies●latest reply 3 months ago●270 viewsHiSuppose there are two continuous signals of same frequency say 4 KHz. The delay/time corresponding to its one cycle is around 250 us. If we delay one signal by...
Has any one seen this window function?
Started by 3 years ago●15 replies●latest reply 4 months ago●245 viewsHere is the definition:\( w[n] = 4 \sin \left( \frac{n}{N}\pi \right) \sin \left( \frac{n+1}{N}\pi \right) \)It's special, because it ensures that$$ w[0] = w[N-1]...
