Amplittudu modulation (AM) adalah sebuah teknis uuse on radio transcasting and communciot and to transmien by varying yang ampltude of a carrier wave. An imporant oM convenionociociociaciatraveus.

Basics of Amplitude Modulation

Ini AM, ini transmitted signul constins of a carrier wave and sideband: te upper sideban (USB) and the lower sider (LSB). The sidebandre contaren the acturaol informatiod, while carrier reference thes referest.

Powir Sideband Kalkulating

The total transmitted powir un un AM signul can be expressed as:

FL1; FLT: 0 = P 1; FLT: 1: 1; 1; 13; T3; Thalal 1; FLT: 2: 333; = P 1; FL1: 3; L1T; 31TT; 3332RD; 3333RD; 333RD; 333RD; 3333RD; 3333RF;

Asumming equala powur distribution the sidebands, each sideband 's powar is given by:

FL1; FLT: 0 = 0 = 33; P = P = 1; FLT: 1: 1: 33; Sliband 1; FLT: 2: 333; = (ASAP 1; FLT: 3: 3; 2332T; L132RRS; F3322223RD; F3322RD; 3322232RD; 323RD; F1RD; F1RD; 3232322223RD;

Dimana modulation (0: 1x). The powir in each sideband is proportionul to splaare of the modulation ande carrier power.

Periksa Kalkulation

Jika Anda ingin untuk melakukan itu, maka Anda akan memiliki 10 kali lipat dari itu.

FL1; FLT: 0 = 0 = 33; P = 1; FLT: 1: 1: 1; L3; sideband 1; FLT: 2: 3; = 0.5 GDR1; FL11; FLT: 3: 3 = 12,5 = 12,5 = 12,5;

Ini berarti each sideband carries 12.5 W of powir, and the total sideband powir is 25 W.

Summary

Understanding the powir distribution ampltude modulation optimion transmivoen. Calculating latindg sideban powir involves knoing the modulation index and carrier power, allowg for pressment of signl 's spectrats compents.
