Correlation of the Amplitude of Successive Pulses of CP 0328

Article metrics


AN investigation of the variation in amplitude of individual pulses from pulsars was undertaken on June 29–31 using the 46 m antenna at Algonquin Radio Observatory with the receiver usually used in the long baseline interferometer programme. The system specifications were: right-hand circular polarization, a centre frequency of 408 MHz, r.f. bandwidth of 4 MHz, and a system noise of 300 K. The signals were detected, passed through a low-pass filter of variable bandwidth with the cut-off frequency set to 10 Hz for the observations reported here, and recorded on a high-speed chart recorder. Of the twenty-six pulsars investigated only CP 0328 had sufficiently intense pulses to warrant further analysis. A typical record is shown in Fig. 1.
