embedded system, spectrogram, FFT, operating systemAbstract
This paper describes the implementation of a digital spectrogram on an embedded system, with the aim of allowing the visualization of the effects of applying digital filters and Fast Fourier Transform over a signal. The FreeRTOS operating system was used to facilitate the management of processing resources.Downloads
