Sampling Rate conversion with arbitrary and variable ratios

Hi Folks, I would like to ask you about a non-very common topic... Arbitrary Ratio Sampling Rate conversion... With this, I want to refer to resampling of...
ADXL1002 signal processing for condition monitoring application

I am a fresher in the field of condition monitoring. I have been working on a condition monitoring project for rotating machines using ADXL1002 accelerometer. I...
Difference between averaging and decimation on oversampled data

In 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...
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

Suppose 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,...
ChatGPT's idea of a computationally efficient digital filter - ha ha ha...

Design a computationally efficient digital filter which can extract a 1 kHz signal between 1000 Hz and 2000 Hz from a digital input signal with a sample rate of...
How do I produce a covariance matrix from IQ samples?

Dear Colleagues,I'm working with BLE AoA Localization. My problem is: What to do exactly with IQ(in phase-quadrature signals) information from an antenna array in...
Delay estimation using cross correlation

HiSuppose 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?

Here 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]...
