Weba spectrogram. An underlying objective of the lab is to learn more about the spectrogram. There are several specific steps that will be considered in this lab: 1.Synthesize a beat-note signal with a MATLAB M-file, and display its spectrogram. 2.Study the frequency resolution of the spectrogram for two closely spaced sinusoids. 3. WebSpectrogram Frequency Range and Sampling Rate. Frequency Range and Sample Rate. As you noticed, a spectral representation has a precise frequency range (Fmax). ... Aliasing – from alias – is an effect that makes different signals indistinguishable when sampled. It also refers to the difference between a signal reconstructed from samples and ... family store roth
