Web© KKL 3 We must find a way to quantify (=to measure) the performance of a modulation scheme. We use the signal-to-noise ratio (SNR) at the output of the receiver: WebIn 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.
