Vedclass · Answer

(A) In a superheterodyne receiver,the process of tuning involves selecting a specific broadcast station signal. This is achieved by changing the frequency of the local oscillator. By varying the local oscillator frequency,the difference between the incoming radio frequency $(f_r)$ and the local oscillator frequency $(f_o)$ is kept constant,which is known as the intermediate frequency $(f_i = |f_r - f_o|)$. Therefore,tuning is essentially the act of varying the local oscillator frequency to match the desired station.
