Question

A super heterodyne receiver is designed to receive transmitted signals between 5 and 10 MHz. The tuning range of the local oscillate for IF frequency 600 kHz for high-side tuning would be (A) 4.6 to 9.6 MHz (B) 5.6 to 10.6 MHz (C) 4.6 to 10.6 MHz (D) 5.6 to 9.6 MHz

For high-side tunning fL O=fm+fI F, PI F=600 kHz =0.6 MHz ⇒ fL O L=5+0.6=5.6 MHz f text LOU =10+0.6=10.6 ,MHz

Q. A super heterodyne receiver is designed to receive transmitted signals between $5$ and $10 M Hz$ . The tuning range of the local oscillate for IF frequency $600 k Hz$ for high-side tuning would be

$4.6$ to $9.6 M Hz$

$5.6$ to $10.6 M Hz$

$4.6$ to $10.6 M Hz$

$5.6$ to $9.6 M Hz$

For high-side tunning
$f_{L O} = f_{m} + f_{I F}, P_{I F} = 600 k Hz = 0.6 M Hz$
$\Rightarrow f_{L O L} = 5 + 0.6 = 5.6 M Hz$
$f_{LOU} = 10 + 0.6 = 10.6, M Hz$
