An upward or downward transition serves as a 'kick' to the filter, which might result in some kind of output. Example, an LC filter might tend to ring at the resonant frequency.
Then to perpetuate the ringing, the transitions can be input at proper times although it does not have to be only at the resonant frequency (f). Possibilities are f/2, f/3, f/4, etc. One cycle of each or more than one cycle.
Or f*3 or f*5.
Notice that it won't work to apply f*2 or f*4 because they transition in a direction that opposes the ringing waveform.
