Which among the following is the characteristic value of Intermediate Frequency (IF).

Which among the following is the characteristic value of Intermediate Frequency (IF) while converting the carrier frequencies from medium waves to short waves in case of Super-heterodyne Receiver ?

a. 430 KHz
b. 480 KHz
c. 450 KHz
d. 455 KHz

Correct Answer : d. 455 KHz

Explanation :
Fixing the IF value to about 455 Kilohertz is the major advantage of uperheterodyne receiver due to which all of its the successive stages operate at a fixed frequency & however the system design becomes more simpler along with an improvement of system performance.
