Give breif explanation for intermediate frequency stage?
In the recieving antennae the carrier frequency is changed into a lower frequency by a process called intermediate frequency (IF) stage preceding the detection. Hope you understand my answer. ALL THE BEST.......
Mixing the carrier signal with any small or local type oscillator signal will produce the difference in frequency called beats andd therfore IF frequency emerges which is highly used in Electronics Communication Engineering.
In communications and electronic engineering, an intermediate frequency (IF) is a frequency to which a carrier wave is shifted as an intermediate step in transmission or reception.[1] The intermediate frequency is created by mixing the carrier signal with a local oscillator signal in a process called heterodyning, resulting in a signal at the difference or beat frequency. Intermediate frequencies are used in superheterodyne radio receivers, in which an incoming signal is shifted to an IF for amplification before final detection is done.
