WebAn image frequency is one which lies equidistant from the LO frequency, but on the opposite side, as shown in the drawing below (down-conversion shown). In this case, we assume the frequency band … Web4 apr. 2024 · A significant drawback of real mixing is that both the desired signal and unwanted image have equal energy and are separated by twice the baseband signal frequency. It is not practical to filter out the unwanted image in a real mixer because the baseband signal frequency is usually low. WebIn up-convert mixers, image frequency will be unwanted sideband, which has amplitude at level same as wanted desired signal. This image frequency need to be filtered out in up conversion. There are specially … bowsers inside story maghic door move
