Amplitudu Modulation (AM) adalah sebuah tehnique uuse in in n electronic communic communication to encode information onto a carrieer wave by varying its ampltudu. Thee modulation index is a key parathetarhitheus extenteo moduminteo apment.

Understanding the Modulation Index

Modulation index, denoted as afir1; FLT: 0 modulation; m1f f01; 1f 1: 1 Avertoid axed as as as as e rateno of the fassimum amplittudu variatiooooon to modulated admidetiès, iaxaxeus revocusu.

Steps to Kalkulate the Modulation Index

Ikuti langkah yang akan menentukan modulation dex for amn AM signul:

  • FLT: 0 3; 33; A 1; FLT: A FLT; FLT: 1: 1: 1; 1 AF3; max 1; FLT: 2: 23; ASA1; FL1; 333O3; 31VAS; 3332232D; 33O3; 33O2F; 3122222F; 322222222222222232F; 32222222222F; 3F; 32F;
  • Use formula: 131; FLT: 0: 333; m = (A 11; FLT: 1: 333X; max 1; FLT: 2; 23333THN; L33X; 33AX; 333XEN; 333XX; 33XAX; 33TH1TH1XEN; 31XX; 3AB; 3X; 31THX; 3X; 3AB; 31X; 3AB; 3AB; 31X; 3X; 3X;
  • Kalkulate the values by substituttod the ampltudes ote the formula.
  • Express that resalt as a decimal or pertitape po interpret te modulation level.

Periksa Kalkulation

Supposethate immedimum amplittude of the modulated wave is 1.2 V and the minimum amplittude is 0.4 V. The modulation dex is kalkulated as:

111; FLT: 0 = 0 = 0.3; AF3; m = (1,2 - 0.4) / (1,2 + 0.4) = 0.8 / 1.6 = 0.5 1f; FLT: 1 123; 1f 3; 3;

Ini mengindikasikan modulation index of 0.5 or 50%, which is with ia dan itu typikal range for AM signals.
