Method of converting bit combinations into a pulse position modulation signal and arrangements for carrying out the method.

摘要

The method converting bit combinations with a given number of bits into pulse position modulation words, uses a corresp. number of storage elements for serial storage of the bits within each bit combination, with parallel read-out of the storage elements to supply the parallel inputs of a demultiplexer which provides a parallel output bit pattern dependent on the parallel inputs. This bit pattern is fed to a parallel-series converter controlled by a time slot clock signal. Pref. the time slot clock signal is obtained by dividing the bit combination clock signal by a factor corresponding to the number of bits and multiplying by the ratio between the number of time slots and the number of bits.
