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
