Carrier wave equation

The AM modulator must produce a carrier signal that varies in amplitude according to the shape of m(t). Because they are of the same frequency, no envelope is produced as they are changing at the same rate .12 Mar 2013

They have sufficient power and frequency to be transmitted without interference and easily . By imposing the input signal on to a carrier signal, the input signal can be transmitted along with carrier signal. This is known as modulation. The frequency of the carrier must be higher than that of the input signal.16 Kas 2017

A carrier wave is a pure wave of constant frequency, a bit like a sine wave. By itself it doesn’t carry much information that we can relate to (such as speech or data). To include speech information or data information, another wave needs to be imposed, called an input signal, on top of the carrier wave.

When the amplitude of the modulating signal is greater than the amplitude of the carrier, distortion will occur . 5. What is the effect of distortion? Explanation: Distortion occurs when the modulating signal amplitude is greater than the amplitude of the carrier, causing incorrect information to be transmitted.
