An investigation of the frequency dependence of the radio emission of pulsars promises to contribute considerably to the understanding of such outstanding questions as:

  1. 1. Is the emission mechanism narrowband or broadband?

  2. 2. What is the coherence time of the radiation?

  3. 3. Does a radius-to-frequency mapping exist?

  4. 4. Is pulsed radiation absorbed in the magnetosphere?

The 100-m telescope in Effelsberg is satisfactorily sensitive in the GHz frequency range so that we could observe averaged pulses up to 22.7 GHz (Bartel et al., 1977; Bartel et al., 1978) and single pulses at 8.8 GHz (Bartel et al., 1980a), which are the highest radio frequencies respectively at which pulsars have been detected. Therefore quite naturally the analysis of the frequency dependent pulsar emission became one of the focal points of interest in pulsar research at the MPIfR.
