The first block of the digital part of the Sub-Nyquist project. Takes 4 channels from the A2D which are sampled at high frequency (60[MHz]) and outputs 12 channels to the rest of the blocks at a lower sampling frequency (20[MHz]). The main purpose of this digital block is to use less analog hardware and to minimize costs.

Project Goal
- Receiving 4 high-rate channels and expanding each to 3 low-rate channels.
- Iterating over each expanded channel and outputting a different slice each time.
