ABSTRACT:
An apparatus for altering frequencies such that any one of a plurality of input frequencies automatically becomes another specified frequency. The value of the output frequency will remain constant regardless of which input frequency chosen, as long as the input frequencies have the relationship a, 2a, 4a, 8a . . . An input signal is received by a descending cascade of units composed of multipliers and filters. The multiplier portion of each unit must be in series with and receive the input stimuli before the filter portion of each unit. Each multiplier portion of the unit must also have a control input of a predetermined value. A phase lock loop inside of a feedback loop compensates for instantaneous variations of frequency in the input signal. This feedback loop is connected from the multiplier-filter unit to the control input for each multiplier portion.
