In this Physics video lecture in Hindi for class 12 we explained the working of wireless communication system with block diagram. Electrical signal is produced by the microphone which is input transducer. The electrical signal is modulated with a high frequency signal known as carrier wave with the help of modulator. The modulated signal is amplified and then transmitted in the form of electromagnetic waves through the transmitting antenna. The signal is traveled through the space known as the communication channel and received by the receiving antenna. Then the modulated signal is demodulated using demodulator. The signal is then amplified and sent to the speaker known as output transducer.
Communication is the act of sharing or exchanging information with someone, for example by speaking, writing, or sending radio signals.
