In this video, what is modulation, why the modulation is required in communication and different types of modulation schemes are explained briefly.
By watching this video, you will learn the following topics:
0:00 Chapters
0:28 What is Modulation?
2:06 Why Modulation is Required?
5:06 Types of Modulation
6:00 Continuous-wave modulation (AM, FM, PM)
7:18 Pulse Modulation (PAM, PWM, PPM, PCM)
10:05 Digital Modulation (ASK, FSK, PSK)
What is Modulation?
Modulation is the process where one of the properties of the periodic signal (the carrier wave) like amplitude, phase or the frequency is altered according to the message signal (Baseband signal).
Why Modulation is Required in Communication
1) Ease of Radiation (To reduce the antenna size)
2) To reduce the interference
3) To allow the multiplexing of the different signals
Types of Modulation
1) Analog Modulation (Message signal is analog in nature)
2) Digital Modulation (Message signal is digital)
Analog Modulation can be further classified as
1) Continuous-wave modulation
Amplitude Modulation (AM)
Frequency Modulation (FM)
Phase Modulation (PM)
2) Pulse Modulation
Pulse Amplitude Modulation (PAM)
Pulse Width Modulation (PWM)
Pulse Position Modulation (PPM)
Pulse Code Modulation (PCM)
Mainly there are three types of Digital Modulation
1) Amplitude Shift Keying (ASK)
2) Frequency Shift Keying (FSK)
3) Phase Shift Keying (PSK)
This video will be helpful to everyone in understanding what is modulation, why it is used, and what are the different types of modulation schemes.

🎯 Key Takeaways for quick navigation: 00:12 📡 Communication involves exchanging information wirelessly or through wires between distant points. 01:32 📶 Modulation is the process of changing a property of the carrier signal (amplitude, phase, or frequency) according to the baseband signal, enabling transmission of the baseband signal over long distances. 02:25 📏 Modulation is used to reduce the size of the antenna and manage interference in wireless communication. 05:32 🔢 Modulation can be categorized into analog modulation and digital modulation, with various subtypes in each category. 10:06 🔄 Digital modulation includes techniques like Amplitude Shift Keying (ASK), Frequency Shift Keying (FSK), and Phase Shift Keying (PSK) to represent digital bitstreams.

To my considration there is always indeed a change in frequency, otherwise there would be no transmitting.

Please clarify. Modulation, we use to transform low frequency signal into high frequency signal so that it can reach upto long distance. Confusion is that high frequency applications like mmWave, visible light communication are operational at short distances. 🤔 what is the relation here of frequency with the distance? Am I ignoring any other parameter? Communication expert, Please response. THANK-YOU

@tylerdavault9604 2 жыл бұрын

Certain frequencies get absorbed by air. Generally, lower frequencies travel farther because few elements in air will absorb the wavelength. Note, stoichometric spectroscopy can be used to determine with frequencies any given element/compound will absorb/reflect.
