A superhet receiver that does use a simple ceramic filter in the 455KHz IF, but instead of selecting the IF (plus USB, minus LSB), to select the IF+30KHz with a single ceramic filter. This will select 2 sidebands that are +30KHz and -30KHz away from 455KHz instead of close to it. One of these sidebands (say LSB) can be easily filtered ... WebWide Band Reject Filter uses a low pass filter, a high pass filter, and an amplifier. To get the actual result of the wide band stop filter, the low cut-off frequency of the Low Pass Filter has to be larger than the high cut-off frequency of the high pass filter. Also, the pass band of the high and low pass filters has to be equal. Here F1 > F2. ean editor
