Modulation: The Key to Understanding Communication Systems | AM 2.1

Modulation, what is modulation, and why we need modulation in communication system is addressed in this video. We deliberate on the use of modulation with respect to efficient radiation, relationship of wavelength and frequency, and antenna size of GSM as well as antenna size of cage antenna. Also, topics of multiplexing and multiple access which are applications of modulation are pointed out with an application of video spectrum that utilizes VSB as video modulation technique and FM modulation for audio transmission. Furthermore, the aspect of attenuation at high frequencies and its link with modulation is pointed out with reflection on mmWave and 5G technology. The video also includes bandwidth and SNR relationship linked through Shannon capacity and outlines analog modulation schemes such as AM, FM, and PM and hint towards Digital modulation schemes and Shift Keying.
