Question

A single conversion receiver with a 9 MHz IF has a local oscillator operating at 16 MHz. The frequency it is tuned to is:

a) 7 MHz
b) 9 MHz
c) 16 MHz
d) 25 MHz

Answer 1

The frequency to which the receiver is tuned is either 25 MHz or 7 MHz since the local oscillator operates at 16 MHz with an IF of 9 MHz.

Step-by-step explanation:

The question pertains to radio frequency and the operation of a single conversion receiver. A single conversion receiver with a 9 MHz intermediate frequency (IF) that has a local oscillator operating at 16 MHz is tuned to a specific frequency. The frequency to which it is tuned can be found by either adding or subtracting the IF from the local oscillator's frequency. In this case, the possible received frequencies would be either 16 MHz + 9 MHz or 16 MHz - 9 MHz, which gives us 25 MHz or 7 MHz, respectively. Therefore, the correct answer is that the frequency it is tuned to is 25 MHz or 7 MHz.
