21	Power spectral density vs. FFT bin magnitude
9	What is a $BT$ (Bandwidth-Time) product with reference to modulation?
7	Applying DFT twice does not actually reverse an array. Instead, the first element stays in place while the rest of the array is reversed. Why?
5	How do I calculate the range of a fixed-point number with $a$ integer bits and $b $ fractional bits?
4	Can we choose a sampling frequency to remove unwanted noise at a specific frequency?
