Question

Please answer question 4, why is it that option?

4. In a a) b) superheterodyne receiver, the inputs to the Mixer stage are: IF amplifier and RF stage IF amplifier and Local oscillator c) Detector and RF stage d) RF stage and Local oscillator 5. In a superheterodyne receiver, a varactor diode: b) a) is placed in series with the tank inductor to provide tracking at the low end of a large frequency band. is placed in parallel with each section of the ganged capacitors of the tank to provide tracking at the high end of a large frequency band. c) is placed in an RF amplifier to provide for proper neutralization. d) is placed in a tank circuit to provide for electronic tuning. 6. A single stage that creates the LO signal and mixes it with RF to produce the IF is called: a) An autodyne mixer. b) A cross-modulator. c) A lattice modulator.
