Spectrogram in matlab

WebUtilice la función spectrogram para calcular la STFT de la señal. Divida la señal en segmentos, cada uno de M = 49 muestras. Especifique L = 11 muestras de solapamiento entre segmentos contiguos. Descarte el último segmento, el más corto. Aplique una ventana de Bartlett a cada segmento. WebA spectrogram is a visual representation of the Short-Time Fourier Transform. Think of this as taking chunks of an input signal and applying a local Fourier Transform on each chunk. …
