Modulated local oscillator |
摘要 |
<p>A method of performing a frequency conversion of a radio frequency (RF) information signal by mixing the information signal with a modulated signal from local oscillator. The local oscillator signal is modulated with a periodic, coded or pseudo-random modulating signal. A system for generating an intermediate frequency (IF) output signal from the information signal is also provided. <IMAGE></p> |
