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...
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]...
I asked the ChatGPT artificial intelligence (AI) software to write a song about the Nyquist Sampling Theorem in the style of Bob Dylan. Here's what the AI produced:Verse...
Finding delay b/w two signals using MATLAB 'gccphat'

Hi allI am simulating signals on two hydrophones H1 and H2 of linear array which are at a distance 'd' from each other. The geometry is shown below:Assuming Plane...
Hello I am looking to implement a sigmoid function as an activation function for ML(I do know that there is now a ML Related). I need to implement this is a fixed...
