Sensitivity & Drawbacks of Tuned Radio Receiver
Q. Drawbacks of Tuned Radio Receiver are- Published on 14 Oct 15a. Oscillate at higher frequencies
b. Selectivity is poor
c. Bandwidth of the TRF receiver varies with incoming frequency
d. All of the above
ANSWER: All of the above
The TRF receivers give unstable output as they have the tendency to oscillate at higher frequencies. The selectivity of the TRF receivers is poor to distinguish the desired signal from the undesired signal. With tuning range, there is variation in bandwidth with incoming frequency. The receiver selects adjacent undesired frequencies with the desired frequencies due to variable bandwidth.
