spectrogram is a function used to plot the spectrum of short-time fourier transform (used to determine the sinusoidal frequency and phase content of local sections of a signal) of input signal, whereas pspectrum function returns the power spectrum (used to analyze signals in the frequency and time-frequency domains) of input signal.
