ABSTRACT:
A digital frequency quadrupler which provides output pulses at a rate equal to four times the number of input pulses. The input frequency range is extended by logic which allows additional pulses to be inserted in the output as the input frequency increases causing overlap between adjacent pulses. When the maximum upper range limit is reached the quadrupler saturates, that is, the output frequency becomes constant.
