The carrier frequency of a transmitter

網頁In amplitude modulation, it is the voltage level of the signal to be transmitted that changes the amplitude of the carrier in proportion, see Figure 63.1. With no modulation, the AM carrier is transmitted by itself. When the modulating information signal (a sine wave) is applied, the carrier amplitude rises and falls in accordance. 網頁In document Mcq in Est by s. Cuervo of Excel (Page 56-81) 1. Determine the power saving in percent when the carrier is suppressed in an AM signal modulated to 80%. 2. Find the percent of modulation of an AM signal if 8 V signal carrier is modulated by 3 different frequencies with amplitude 1 V, 2 V and 3 V. 3.
