Детектор радіосигналу з використанням PLL генератору та мікроконтролера

Abstract

The radio scanner is a compact device equipped with a PLL generator for precise frequency tuning and a microcontroller for signal processing. It utilizes two filters to enhance signal quality and includes a screen and speaker for dis- playing information and user notifications. This device efficiently detects and analyzes radio signals on programmed frequencies, ensuring quick response to radio frequency activity in the current location and user convenience.
