Case : Read the passage and answer the question(s). A message signal of frequency 10 kHz and peak voltage 10 V is used to modulate a carrier of frequency 1 MHz and peak voltage 20 V. |
What is the modulation index ? |
0.5 0.75 0.45 0.85 |
0.5 |
\(\mu\) = \(\frac{A_{m}}{A_{c}}\) = \(\frac{10}{20}\) = 0.5 |
