Frequenzumsetzer zum spektralen Umsetzen eines Startsignals und Verfahren zur spektralen Umsetzung eines Startsignals

DE1004059939 A UPAB: 20060714 NOVELTY - Frequency converter (100) has selecting device (102) for selecting plurality of partial signals (TS1-TS4) based on I-component or Q-component. One partial signal comprises component values that can be selected according to grid, and another partial signal comprises Q component values selected according to grid. Weighting device (104,106,108,110) is for weighting partial signals. DETAILED DESCRIPTION - Device for weighting each of partial signals uses weighting factor in order to obtain plurality of weighting signals. Adding device (112) is for adding up plurality of weighting signals (GS1-GS4) in order to obtain end signal having target frequency. INDEPENDENT CLAIMS are also included for the following: (A) Method for spectral conversion of starting signal; and (B) Computer program for execution of the method USE - For the spectral conversion of a starting signal having an actual frequency into an end signal having a target frequency. ADVANTAGE - Ensures a simple and efficient way of executing spectral conversion
