Filters local in time while rejecting low frequencies

Dear Fieldtrip, We would like to do time-frequency plots using filters that
are quite local in time (less than about 2 cycles) and yet have relatively
low sensitivity to low temporal frequencies. For example, filters defined on
log frequency might do the job in being insensitive to low frequencies, but
are they sufficiently local in time?
thanks,
Stan Klein
