A 1000 H carrier wave modulated 40% at 4000 H is applied to a resonant circuit tuned to a carrier frequency and having = 140. What is the degree of modulation after passing the wave through this circuit? |
| Answer» Resulting depth of modulation is given by : when δ = fc = 1000 x 103 Hz fm = 4 x 103 Hz δ = m0 = = = 0.27 . | |
