Single Sideband Modulation via the Hilbert Transform -

SSB modulation requires the shifting of the message signal to another center frequency without creating pairs of frequency components X(f-fo) and X(f+fo) as in the case of the DSB modulation, i.e., avoiding the need to filter either the upper or lower sideband. This can be done by using a Hilbert Transformer.

The FM Ceramic Filter Page - EarMark

The electrical function that ceramic filters perform is that of a passive bandpass filter centered on 10.7 MHz. A bandpass filter passes its center frequency, while rejecting frequencies to each side of the center. The quality, or "Q" factor of a bandpass filter is a measure of how sharply it rejects the frequencies to each side of the center frequency. The Q of FM ceramic filters is not specified directly,
