A super heterodyne receiver operates in the frequency range of 58 MHz − 68 MHz. The
intermediate frequency 𝑓𝐼𝐹 and local oscillator frequency 𝑓𝐿𝑂 are chosen such that 𝑓𝐼𝐹 ≤ 𝑓𝐿𝑂. It is required that the image frequencies fall outside the 58 M Hz − 68 MHz band. The minimum required 𝑓𝐼𝐹 (in MHz) is ________.
