   If the baseband signal is band-limited, then there is a finite maximum frequency of the corresponding sinusoids. One can take this sum and modulate it on a carrier signal of some other frequency in a simple way: by just multiplying the baseband and carrier signal (also called “mixing”).

   To transmit signals with frequencies required by the communication channel, the transmitter centers the spectrum of the information signal at the transmission frequency. This process of shifting the frequency spectrum of a signal is called modulation. As an example human voice spans a 4 kHz range or bandwidth, and is centered at 0 kHz. In order ...

   Modulation is a technique that changes the characteristics of the carrier frequency in accordance with the input signal. Figure 1.1 shows the conceptual block diagram of a modern wireless communication system, where the modulation block is shown in the inset of the dotted block. As shown in the figure, modulation is performed at the

   Typically the objective of a digital communication system is to transport digital data between two or more nodes. In radio communications this is usually achieved by adjusting a physical characteristic of a sinusoidal carrier, either the frequency, phase, amplitude or a combination thereof.

   How to modulate a signal?

   • Mathematically, we will find it convenient to use complex exponentials; with that notation, the process of modulation involves two important steps: 1. Shape the input to band-limit it. Take the input baseband signal and apply a low- pass filter to band-limit it.
