### Overview

The project involves the following components:

- **System Architecture**: The architecture of the digital system, including the data path, control path, and top-level system design.
  
- **Filter Design in MATLAB**: Designing a FIR LPF using MATLAB's Filter Designer tool, specifying frequency requirements and obtaining filter coefficients.

- **Filter Implementation in Verilog**: Implementing the FIR LPF in Verilog, integrating it into the larger DDS system architecture.

- **Verification and Simulation**: Validating the Verilog implementation through simulation and comparing results with MATLAB's ideal plots.
