== Project Objective
{{{#!html
Overview
In recent years, there has been a desire to expand the bandwidth of communication standards such as LTE and 5G. However, at many of the bandwidths that are desired to be used, there exist legacy signals that cannot be interfered with. This is made even more difficult by Adjacent Channel Interference (ACI), when signals with very close, but distinct frequencies still impede each other.
Goals:
- Framework: Build the framework to test signal avoidance.

Week 1 Presentation
Summary
- Familiarized with breadboard computer components: ICs, logic gates, registers, breadboards, wires, and connectors.
- Learned about fundamental computer components: Fetch-Execute Cycle, CPU, RAM, ALU, and BUS.
- Explored the Fetch-Execute Cycle: Fetch, Decode, Execute.
- Studied the CPU: functions, clock, registers, and ALU.
- Understood RAM: its function, volatility, and direct access capabilities.
- Examined the ALU: performs arithmetic and logical operations.
- Investigated the BUS: facilitates communication between CPU, memory, and peripherals.
- Planned tasks for next week: model and test the ALU using TinkerCad, begin detailed documentation, construct the clock monitor, and build the registers.
