The superhet rodyne receiver is quite important in a radio receiver.

It enable the receiver to use a single frequency as the center frequency of the band-pass filter. this frequency is the Intermediate Frequency (IF).
The received signal is going through a frequency translation (in practice it goes through a mixer), which makes it
IF centered.

It should be noted that a static filter is much easier to build and is much more efficient.
