check the both statements are true or false.1.Tuned RF receiver works well at low frequency but not work well at high frequencies.2. Local oscillator frequency in super heterodyne receiver is selected always higher than fs to get difference of IF and so it is called super heterodyne. Group of answer choicesTrueFalse

If a superheterodyne receiver is operate at 450KHz IF and we want to listen 1100KHz station then what should be frequency of local oscillator ?Group of answer choices1550KHz450KHz900KHz550KHz
