Advancements in Signal Processing Through Electrical Circuits and Systems

Abstract

Signal processing forms the backbone of modern communication, control, and multimedia systems, relying heavily on efficient electrical circuit implementations. With the continuous demand for high-speed data transmission, enhanced image processing, and secure communication, advancements in circuit design for digital and analog signal processing have become increasingly vital. This paper explores the role of electrical circuits in implementing digital filters, fast Fourier transform (FFT) processors, and adaptive filtering techniques. It highlights innovations such as low-power DSP architectures, VLSI-based circuits, and reconfigurable systems-on-chip that provide flexibility in real-time applications. Special emphasis is placed on hardware accelerators for machine learning and AI-driven signal processing, where custom-designed circuits drastically reduce latency. Challenges such as noise immunity, circuit complexity, and integration into heterogeneous architectures are analyzed. The study shows how electrical circuits not only enable signal processing but also enhance the accuracy, reliability, and speed of complex systems.
