A super heterodyne radio receiver with an intermediate frequency of 455 KHz is tuned to a station operating at 1200 KHz. The associated image frequency is----------- KHz |

Answer» In most receivers the local oscillator frequency is higher than incoming signal i.e. f0 = fs + fsi f0 – Local oscillator frequency fs = Signal freq fsi = Image freq fsi = fs + 2IF = 1200+910 = 2110 KHz |
