| 21. A system for processing signals, the system comprising:
a single chip having an integrated Bluetooth® radio and an integrated FM radio comprising:
at least one processor that enables tuning to a particular frequency within a range of FM channels based on an IF frequency
that includes an integer multiple of the channel spacing between neighboring allocated FM channels within said range of FM
channels, offset by at most one-half said channel spacing; and
said at least one processor enables determining, utilizing a frequency error, whether said particular frequency comprises
an on frequency channel, wherein said frequency error is based on said IF frequency.
