Low-Pass Filter (LPF)
This is fundamental knowledge according to Shaheer.
A low-pass filter (LPF) is a circuit that only passes signals below its cutoff frequency while attenuating all signals above it.

I briefly saw this in CS370 when looking at Fourier Transform.
- Yes, you work in frequency domain, and just remove the low frequency values
You can also implement this in C++.
