Resumen

This study presents the design and implementation of a two-channel digital oscilloscope and spectrum analyzer based on the Teensy microcontroller, with data transmission via USB CDC. The system includes a signal conditioning stage with digital filters and operational amplifiers to ensure proper adaptation before analog-to-digital conversion, performed by the microcontroller’s internal ADC. With a sampling rate of up to 100 kHz, the system enables time and frequency domain analysis using the Fast Fourier Transform (FFT). A PC-based graphical interface allows real-time data visualization and processing. This development provides an efficient solution for signal analysis in research and educational applications.
