WebNow it is easy to see that this image has a horizontal frequency of 10. Let's increase the frequency by a factor of 10, so that n = 100. f = 100/800 = 1/8 = 0.125 repetitions/px: As … Web18 feb. 2024 · Spectral analysis of the image is necessary to design very selective filters like the previous one. For performing the filtering, there is a choice between filtering in the … WebBoth the RF and IMAGE frequency will be translated to the same IF frequency. With a 10.7 MHz IF frequency, the image is always outside of the FM broadcast band. Therefore, strong in-band FM signals are never to be found at the image frequency. A preselection filter can be used to reject this image that is 21.4 MHz away from the desired RF signal. thioact d4
