This looks like a rectifier. The VCO free-running frequency f out is adjusted externally with R 1 and C 1 to be at the center of the input frequency range. The lock range f L and capture of PLL is given by:. Important Point :. SNR Input. Start Learning. To maintain the tuning correct To reduce the volume of loud passages of music To increase the amplification at high frequencies To maintain the same volume of the output when stations of different strength are received.

Answer Detailed Solution Below Option 4 : To maintain the same volume of the output when stations of different strength are received. AGC maintains a constant level of the output signal based on the received signal nature, i. AGC can handle problems like overloading and fading in the receiver.

Answer Detailed Solution Below Option 1 : 1. From the above figure, it is evident that the balanced modulator is given the DPSK signal along with 1-bit delay input. Powered by.
