Is a knowledge of the transmitting frequency essential in the design of an FM receiver?

I am supposed to design an FM receiver that can receive in the range 88 to 108 MHz. If I am unaware of the frequency of the transmitter, will I still be able to detect the signal. Can I have a design for such a circuit if that is possible?

It's called a tunable receiver. A typical FM radio is one example, where you can "turn the dial" to set it to receive any frequency between 88 and 108 MHz.

Design of a FM radio is not simple. Nor is construction and troubleshooting of one.

reference has some circuits.
