X
`rarr" IF stage "rarr` Intermediate frequency stage to change the carrier frequency to lower frequency. `Yrarr" Amplifier "rarr` It amplifies the signal i.e. it increases the amplitude of the detected signal to compensate the attenuation of the signal. The detected signal may not be strong enaough to use.
