What is it about?
This study looks at how to create efficient digital filters that help low-power modems work better, especially in devices like mobile phones and Internet of Things (IoT) systems. Using easy-to-understand software tools like MATLAB and SIMULINK, the research shows how two types of filters—FIR and IIR—can be designed, tested, and then turned into real hardware using VHDL and FPGA chips. These filters help improve signal quality while saving energy, which is important for battery-powered devices. The work also compares the strengths of each filter type to help engineers choose the best one depending on their needs.

Why is it important?
With the rise of smart devices and the Internet of Things (IoT), there's a growing need for communication systems that use very little power but still work reliably. This research is important because it focuses on designing digital filters that are both energy-efficient and high-performing—key for extending battery life in small, portable devices. What makes this work timely and unique is the combined use of simulation tools (MATLAB and SIMULINK) and hardware design (VHDL and FPGA), offering a full process from concept to real-world implementation. It helps engineers choose the best filter type for their system, saving time, energy, and development costs.
Perspectives
From my perspective, this publication reflects my ongoing interest in bridging theoretical design with real-world hardware implementation. I’ve always been fascinated by how digital filters shape modern communication systems, especially in energy-constrained environments. What excites me most about this work is how it demonstrates a practical, hands-on approach to solving real engineering challenges—using tools that are both accessible and powerful. I hope it inspires others, especially students and early-career engineers, to explore the full design cycle and appreciate the balance between performance and power efficiency.
