The aim is to increase capacity of the system as the signal can be represented using different phase angles as well as amplitude.

Why modualtion is need?

Without modulation, there's be no way to get any information onto a carrier signal. There are several different types of modulation schemes for radio carriers and almost as many different types demodulators to decode the information so that it can be converted into a usable form. For instance, AM (amplitude modulation), FM (frequency modulation), digital modulation, quadrature amplitude, etc.


What is modulation and how is it used in communication systems Can you provide two examples of how modulation is utilized in modern technology?

Modulation is the process of varying a carrier signal's properties, such as amplitude, frequency, or phase, to encode information for transmission. In communication systems, modulation is used to efficiently transmit data over long distances by converting the information into a form that can be carried by the carrier signal. Two examples of how modulation is utilized in modern technology are: In Wi-Fi technology, modulation techniques like Quadrature Amplitude Modulation (QAM) are used to encode digital data into radio waves for wireless communication between devices. In digital television broadcasting, modulation methods such as Vestigial Sideband Modulation (VSB) are employed to transmit audio and video signals over the airwaves for high-quality TV reception.


What is analog modulation?

Analog modulationIn analog modulation, the modulation is applied continuously in response to the analog information signal.Common analog modulation techniques are:Amplitude modulation (AM) (here the amplitude of the modulated signal is varied) Double-sideband modulation (DSB) Double-sideband modulation with unsuppressed carrier (DSB-WC) (used on the AM radio broadcasting band)Double-sideband suppressed-carrier transmission (DSB-SC)Double-sideband reduced carrier transmission (DSB-RC)Single-sideband modulation (SSB, or SSB-AM), SSB with carrier (SSB-WC)SSB suppressed carrier modulation (SSB-SC)Vestigial sideband modulation (VSB, or VSB-AM)Quadrature amplitude modulation (QAM)Angle modulation Frequency modulation (FM) (here the frequency of the modulated signal is varied)Phase modulation (PM) (here the phase shift of the modulated signal is varied)
