Abstract: We present the results of our project, that involved single pulse observations of several pulsars, with a special aim of searching for low-frequency features in their fluctuation spectra. The majority of our observations were performed at the frequency of 8.35 GHz, using the 100-meter Effelsberg Radiotelescope. In order to examine the pulse-to-pulse intensity modulations, we performed both the longitude- and the harmonic-resolved fluctuation spectral analysis. In case of one of the observed pulsars, PSR B1133+16, we found a strong evidence for an amplitude-modulated low-frequency feature, coresponding to a period of ca. 30 pulsar rotational periods, which we believe to be the circulation period of the underlying subbeam carousel model.
