Timestamps for the different topics covered in the video: 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)
🎯 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.

There are 2 types of modulation. Frequency which is 90 degrees. Amplitude which is 180. F demodulation 270. Band spectrum is the push of one over another of cycles.
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
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.
thank you so much for the amazing video !! @ 4:13 you said each signal is modulated at different carrier frequency does this mean, it is an FM modulation? or regardless of the modulation type? there will be always a change in frequency?
I like your explanation but... I face problem with finding videos... Please decide videos in to groups.. Like this videos are from this subject.. Etc...
Hello, I would like to simulate an amplitude demodulation in the spectrum. Do you know a simulation program with which I can simulate it? Many thanks and best regards Gislain
@@ALLABOUTELECTRONICS excellent video, which helps traine and trainers But kindly explain with working circuit please,it will motivate, thank you keep it up.
