engineering recuitment GATE IN Test Series 2023-24 Mock Test Communication Systems Angle Modulation Frequency Modulation
The diagram shown PLL detector used for demodulation of FM signal.
If the sensitivity of modulator at transmitter is 2 and the sensitivity of VCO at receiver is 4.
Then y(t) is [Note: m(t) denotes message signal before modulation]
1
2 m(t)
2
\(\frac{2}{3}m\left( t \right)\)
3
\(\frac{3}{2}m\left( t \right)\)
4
\(\frac{{m\left( t \right)}}{2}\)
