Abstract

In a circuit arrangement for generating at least two signals of different frequencies at least one pair of frequencies having closely adjacent frequencies f 1 and f 1 ', f 2 and f 2 ', f 3 and f 3 ' are derived from a frequency oscillator having a fundamental pulse f 0 , 52. The circuit may be used to generate modulation frequencies of laser signals 16 for a distance measuring instrument 10. A trigger signal f 5 from a microprocessor 50 is used to generate the different adjacent frequencies. At least one frequency is generated by filtering harmonics from at least one frequency f 10 , f 20 , f 30 , f 10 ', f 20 ', f 30 derived from the fundamental pulse f 0 , 52. The circuit includes switchable splitters 28, 34 controlled by the microprocessor 50 and having sub-splitters (76, 78, 80, 82 Fig 2) and switching means (74, 80, 82, 92). The splitter 34 has shift elements (88, 90).
