Consider a superheterodyne FM receiver designed to receive the frequency band of 1 to 20 MHz with an IF frequency 8 MHz. what is the range of frequencies generated by the local oscillator for this receiver ? an incoming signal with carrier frequency 10 MHz is received at the recevier? An incoming signal with a carrier frequency of 10 MHz is received at the 10 MHz setting. At this setting of the recevier, we also get interference from a signal with some other carrier frequency if the recevier RF-stage bandpass filter has poor selectivity. What is the carrier frequency of the interfering signal?
