I need some good books or references to know the main basics of all kinds of Modulation and Demodulation as a communication engineer student ...
Modulation and demodulation are techniques used in communication systems to transfer information between two points. Modulation is the process of altering a carrier signal to transmit information, while demodulation is the process of extracting the original information from the modulated signal.
Modulation and demodulation are crucial in communication systems because they allow for the efficient transfer of information over long distances without significant loss or interference. They also allow for multiple signals to be transmitted simultaneously without interference.
There are several types of modulation, including amplitude modulation (AM), frequency modulation (FM), and phase modulation (PM). Each type varies in how it alters the carrier signal to transmit information.
Demodulation works by reversing the modulation process. The modulated signal is fed into a demodulator, which separates the carrier signal from the information signal. The information signal is then amplified and filtered to retrieve the original information.
Modulation and demodulation are used in various communication systems, including radio, television, telephone, and wireless networks. They are also used in technologies such as Wi-Fi, Bluetooth, and satellite communications.
