Scientific paper

Two pulsars have been observed at low radio frequencies using a narrow bandwidth to avoid pulse dispersion problems, PSR 1133 + 16 was observed at 26.3 MHz using the University of Florida 640-dipole radiotelescope. PSR 2045-16 was observed at 45 MHz using the MaipuRadio Astronomy Observatory 528-dipole radiotelescope. Digital averaging and period-stacking techniques were used in order to increase the signal-to-noise ratio. Both pulsars were successfully detected by averaging typically 400 to 600 periods. The integrated pulse profile, pulse width and an estimate of the pulse flux density and energy were obtained. The systematic observation of pulsars using both radiotelescopes will be soon started.
