These may be assigned to any combination of low frequency EQ, mid-band EQ and top-end EQ chores. However, all four sections are identical and each of them may be programmed in frequency between 50 Hz and 15 kHz (15 000 Hz).

That is why is it not always necessary to use the AGC stage. Split-band filtering is a great technique where audio signal can be separated into different frequency bands so that each band can be processed separately.

The applicable settings for each band have been simplified so as not to complicate the process with useless parameters.

Many RDS receivers are able to seek the listener’s preferred format automatically. This means that a car radio can switch from a fading station to a stronger one that carries the same variety of music, though not the very same program, as provided by AF switching.
