Question

ACTIVITY
Truth or Lie. Write Truth if the statement about the Tuned Radio Frequency and superheterodyne receiver is correct and
Lie if it is incorrect.
1. In a TRF receiver, the antenna amplifies the radio signal.
2 The tuned radio frequency stages consisted of one or more amplifying and tuning stages
3. Increasing one or more turned circuits will increase the selectivity of the radio receiver.
4. Difficulty in designing at very high frequency, poor audio quality, instability, and poor selectivity are the problems in
TRF receivers
5. The audio amplifier enables the audio from the amplitude modulation signal to be extracted
6. Through the process of ganged tuning, tuned amplifiers are tuned to a single frequency (IF).
7. Tuning of the superheterodyne receiver is through the changing of the local oscillator.
8. A supersonic heterodyne wireless receiver was developed to provide an additional level of fidelity.
9. The IF signals are transmitted through an RF amplifier, and the RF amplifier amplifies the signal and sends it to the
mixer.
10. An audio amplifier amplifies the video signal.​
