摘要 |
<p>A frequency shifter system for providing a varying frequency shift for processing a shifter input signal, comprises first converting means (106) for receiving said shifter input signal and converting said shifter input signal in accordance with a first sampling frequency to provide a converted input signal; and second reconverting means (110) for receiving said converted input signal and reconverting said converted input signal in accordance with a second resampling frequency to provide said frequency shift. A method for frequency shifting to provide a frequency shift for processing a shifter system input signal, comprising the steps of first receiving said shifter input signal and first converting said shifter input signal in accordance with a first sampling frequency to provide a converted input signal; and second receiving said converted input signal and reconverting said converted input signal in accordance with a second resampling frequency to provide said frequency shift. <IMAGE></p> |
