Difference between averaging and decimation on oversampled data
Started by 1 year ago●4 replies●latest reply 1 year ago●573 viewsIn my project I am oversampling the data (12 bit ADC) for the following reasons,1. To relax the antialiasing filter requirements before the ADC.2. Increase or...
Started by Hi All,if you google "fft process gain" you get plenty hits including various analysis down to bin spread concepts.However, I notice that this can be viewed in a...
Single-bit long-range low-power communication
Started by 1 year ago●7 replies●latest reply 1 year ago●218 viewsSuppose I want to send a single bit (like an SOS) from some remote location using a low-power RF transmitter. The transmitter emits a pure tone at some frequency,...

Delay estimation using cross correlation
Started by 1 year ago●6 replies●latest reply 1 year ago●523 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 4 years ago●15 replies●latest reply 1 year ago●306 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]...
