Abstract:
A method and means for translating frequencies, as for example, to correct a frequency error. DELTA. f. sub. d introduced into a carrier signal of frequency f. sub. c, comprising means for dividing the resultant signal frequency (f. sub. c +. DELTA. f. sub. d) by N, resulting in a divided-down frequency (f. sub. c /N+. DELTA. f. sub. d /N), with. DELTA. f. sub. d being reduced to. DELTA. f. sub. d /N, and then heterodyning the divided-down frequency with signal of frequency (f. sub. c +f. sub. c /N) to produce a resultant signal of frequency (f. sub. c +. DELTA. f. sub. d /N), the frequency error remaining at its low, divided level. DELTA. f. sub. d /N. In the case of two or more signals spaced apart by predetermined frequency spacings, such frequency spacings can be reduced to predetermined values by dividing said signals by a common divisor M with the frequency spacings also being divided by M and then heterodyning the divided-down frequencies upwardly to desired frequencies with the frequency spacings remaining at their desired reduced values.
