Assume that super heterodyne receiver consumes an IF frequency of 350 kHz by high side tuning to a transmitter with a carrier frequency of 1200 kHz . What would be the value of an image frequency ?
a. 1550kHz
b. 8400 kHz
c. 1900 kHz
d. 1000kHz
ANSWER: 1900 kHz
Explanation:
Given data :
IF = 350 kHz
Carrier Frequency = fc = 1200 kHz
We know that,
Image Frequency = 2 IF + fc
= 2x 350 + 1200
= 1900 kHz
